Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"" When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

mmc: arm_pl180: Limit data transfer to U16_MAX Currently fetching files bigger that cause a data transfer greater than U16_MAX fails. The reason is that the specification defines the datalength register as a 16 bit wide register, but in u-boot it is used as if it is an 32 bit register. Therefore values greater than U16_MAX cause an infinite loop inside u-boot. U-boot expects to get more data from interface/hardware then it will ever get and therefore inifintely waits for more data that will never come.

With a simple oneline to default to not being the v2 variant, the original ARM MMCI variant works fine with the driver as well. The IP version actually needs to be read out from a register on the ARM versions, but we will simply assume we are running on the original hardware if arm,primecell-periphid is not explicitly specified in the device tree.

mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible. This fixes the following error messages when booting the ST-Ericsson U8500 "stemmy" board with the arm_pl180_mmci driver enabled: MMC: ptm@801ae000 - probe failed: -38 ptm@801af000 - probe failed: -38 funnel@801a6000 - probe failed: -38 tpiu@80190000 - probe failed: -38 etb@801a4000 - probe failed: -38 Cc: Patrice Chotard <patrice.chotard@st.com> Fixes: 6f41d1a17e20 ("mmc: arm_pl180_mmci: Sync compatible with kernel") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com> on stm32f769-disco Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> |

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible. This fixes the following error messages when booting the ST-Ericsson U8500 "stemmy" board with the arm_pl180_mmci driver enabled: MMC: ptm@801ae000 - probe failed: -38 ptm@801af000 - probe failed: -38 funnel@801a6000 - probe failed: -38 tpiu@80190000 - probe failed: -38 etb@801a4000 - probe failed: -38 Cc: Patrice Chotard <patrice.chotard@st.com> Fixes: 6f41d1a17e20 ("mmc: arm_pl180_mmci: Sync compatible with kernel") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com> on stm32f769-disco Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> |

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

Therefore values greater than U16_MAX cause an infinite loop inside u-boot.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com> |

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

With a simple oneline to default to not being the v2 variant, the original ARM MMCI variant works fine with the driver as well. The IP version actually needs to be read out from a register on the ARM versions, but we will simply assume we are running on the original hardware if arm,primecell-periphid is not explicitly specified in the device tree.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com> |

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible. This fixes the following error messages when booting the ST-Ericsson U8500 "stemmy" board with the arm_pl180_mmci driver enabled: MMC: ptm@801ae000 - probe failed: -38 ptm@801af000 - probe failed: -38 funnel@801a6000 - probe failed: -38 tpiu@80190000 - probe failed: -38 etb@801a4000 - probe failed: -38 Cc: Patrice Chotard <patrice.chotard@st.com> Fixes: 6f41d1a17e20 ("mmc: arm_pl180_mmci: Sync compatible with kernel") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com> on stm32f769-disco Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> |

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible. This fixes the following error messages when booting the ST-Ericsson U8500 "stemmy" board with the arm_pl180_mmci driver enabled: MMC: ptm@801ae000 - probe failed: -38 ptm@801af000 - probe failed: -38 funnel@801a6000 - probe failed: -38 tpiu@80190000 - probe failed: -38 etb@801a4000 - probe failed: -38 Cc: Patrice Chotard <patrice.chotard@st.com> Fixes: 6f41d1a17e20 ("mmc: arm_pl180_mmci: Sync compatible with kernel") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com> on stm32f769-disco Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> |

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: arm_pl180_mmci: Simplify code using mmc_of_parse() Simplify the code a bit by using the common mmc_of_parse() function instead of duplicating the device tree parsing code. We can still get a default value for cfg->f_max by assigning it before calling mmc_of_parse(). Another advantage of this refactoring is that we parse more properties now, e.g. "non-removable" can be used to disable CD entirely.

mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible. This fixes the following error messages when booting the ST-Ericsson U8500 "stemmy" board with the arm_pl180_mmci driver enabled: MMC: ptm@801ae000 - probe failed: -38 ptm@801af000 - probe failed: -38 funnel@801a6000 - probe failed: -38 tpiu@80190000 - probe failed: -38 etb@801a4000 - probe failed: -38 Cc: Patrice Chotard <patrice.chotard@st.com> Fixes: 6f41d1a17e20 ("mmc: arm_pl180_mmci: Sync compatible with kernel") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com> on stm32f769-disco Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> |

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com> |

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

Use compatible string used by kernel instead and identify mmci variant using "arm,primecell-periphid" property. Currently, the DM part of mmci driver is only used by STM32 SoCs, that's why the switch case gets only one entry. It will be populated easily with new variant in the future.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

mmc: arm_pl180_mmci: update arm_pl180_mmci_init() prototype Update arm_pl180_mmci_init() prototype by adding struct mmc** param. This is needed before converting this driver to driver model in order to use arm_pl180_mmci_init() in driver model and in none driver model implementation Signed-off-by: Patrice Chotard <patrice.chotard@st.com>

mmc: Split mmc struct, rework mmc initialization (v2) The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

mmc: Remove ops from struct mmc and put in mmc_ops Remove the in-structure ops and put them in mmc_ops with a constant pointer to it. This makes the mmc structure smaller as well as conserving code space (in theory). All in-tree drivers are converted as well; this is done in a single patch in order to not break git bisect.

mmc: Remove incorrect cmd->flags usage There were a couple of drivers that were actually using the flags field of the cmd structure, despite the fact that no one ever *set* that field. When we removed the field, those drivers failed to compile. Replaced the references with the correct usage of resp_type. Signed-off-by: Andy Fleming <afleming@freescale.com>

mmc: Implement card detection. Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.

MMC: PL180: Fix infinite loop with VExpress extended fifo implementation The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.
