arm: Use the WEAK assembly entry point consistently It is a bad idea, and more modern toolchains will fail, if you declare an assembly function to be global and then weak, instead of declaring it weak to start with.

arm: ARMv4 assembly compatibility There is currently a problem that U-Boot can not work on ARMv4 because assembly imlementations of memcpy() and some other functions use "bx lr" instruction that is not available on ARMv4 ("mov pc, lr" should be used instead). A working preprocessor-based solution to this problem is found in arch/arm/lib/relocate.S. Move it to the "ret" macro in arch/arm/include/asm/assembler.h and change all "bx lr" code to "ret lr" in functions that may run on ARMv4. Linux source code deals with this problem in the same manner. v1 -> v2: Comment update. Pointed out by Andre Przywara.

ARM: relocate: Fix Thumb code by using proper label type The generic ARM relocate_code function was using its own function entry point as a relocation base, and it was obtaining that address by using the "adr" instruction on that entry point label. However that label is not just an ordinary label, instead we explicitly mark it as a function start address. Normally that doesn't change much (other than for debugging), but when assembled in Thumb mode, newer versions of the GNU assembler prepare everything for this address being used as the argument to a "bx" call, so make sure bit 0 is set in there to mark this function as Thumb code. Of course this doesn't end up very well when we use this address for the ensuing memcpy operation. To avoid this problem, and to solve it in a robust way, add an extra label, which is not marked as a function entry, and use that for the adr instruction. This lets all assemblers generate the right immediate offset in the "adr" instruction. This fixes in particular ARMv7-M ports when using GNU binutils v2.37 or newer (commit d3e52e120b68 seems to trigger the change in behaviour).

armv7: Add Position Independent Execution support A U-Boot image could be loaded and executed at a different location than it was linked at. For example, Aspeed takes a stable release version of U-Boot image as the golden one for recovery purposes. When the primary storage such as flash is corrupted, the golden image would be loaded to any SRAM/DRAM address on demands through ethernet/UART/etc and run for rescue. To deal with this condition, the PIE is needed as there is only one signed, golden image, which could be however executed at different places. This patch adds the PIE support for ARMv7 platform.

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> |

imx: fix exception vectors relocation in imx27 Commit 3ff46cc4 fixed exception vectors setting in the general ARM case, by either copying the exception and indirect vector tables to normal (0x00000000) or high (0xFFFF0000) vectors address, or setting VBAR to U-Boot's base if applicable. i.MX27 SoC is ARM926E-JS, thus has only normal and high options, but does not provide RAM at 0xFFFF0000 and has only ROM at 0x00000000; it is therefore not possible to move or change its exception vectors. Besides, i.MX27 ROM code does provide an indirect vectors table but at a non-standard address and with the reset and reserved vectors missing. Turn the current vector relocation code into a weak routine called after relocate_code from crt0, and add strong version for i.MX27.

imx: fix exception vectors relocation in imx27 Commit 3ff46cc4 fixed exception vectors setting in the general ARM case, by either copying the exception and indirect vector tables to normal (0x00000000) or high (0xFFFF0000) vectors address, or setting VBAR to U-Boot's base if applicable. i.MX27 SoC is ARM926E-JS, thus has only normal and high options, but does not provide RAM at 0xFFFF0000 and has only ROM at 0x00000000; it is therefore not possible to move or change its exception vectors. Besides, i.MX27 ROM code does provide an indirect vectors table but at a non-standard address and with the reset and reserved vectors missing. Turn the current vector relocation code into a weak routine called after relocate_code from crt0, and add strong version for i.MX27.

armv7: Add Position Independent Execution support A U-Boot image could be loaded and executed at a different location than it was linked at. For example, Aspeed takes a stable release version of U-Boot image as the golden one for recovery purposes. When the primary storage such as flash is corrupted, the golden image would be loaded to any SRAM/DRAM address on demands through ethernet/UART/etc and run for rescue. To deal with this condition, the PIE is needed as there is only one signed, golden image, which could be however executed at different places. This patch adds the PIE support for ARMv7 platform.

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> |

imx: fix exception vectors relocation in imx27 Commit 3ff46cc4 fixed exception vectors setting in the general ARM case, by either copying the exception and indirect vector tables to normal (0x00000000) or high (0xFFFF0000) vectors address, or setting VBAR to U-Boot's base if applicable. i.MX27 SoC is ARM926E-JS, thus has only normal and high options, but does not provide RAM at 0xFFFF0000 and has only ROM at 0x00000000; it is therefore not possible to move or change its exception vectors. Besides, i.MX27 ROM code does provide an indirect vectors table but at a non-standard address and with the reset and reserved vectors missing. Turn the current vector relocation code into a weak routine called after relocate_code from crt0, and add strong version for i.MX27.

arm: relocate the exception vectors This commit relocates the exception vectors. As ARM1176 and ARMv7 have the security extensions, it uses VBAR. For the other ARM processors, it copies the relocated exception vectors to the correct address: 0x00000000 or 0xFFFF0000.
