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.

boot: add support for button commands

With the relatively new button API in U-Boot, it's now much easier to
model the common usecase of mapping arbitrary actions to different
buttons during boot - for example entering fastboot mode, setting some
additional kernel cmdline arguments, or booting with a custom recovery
ramdisk, to name a few.

Historically, this functionality has been implemented in board code,
making it fixed for a given U-Boot binary and requiring the code be
duplicated and modified for every board.

Implement a generic abstraction to run an arbitrary command during boot
when a specific button is pressed. The button -> command mapping is
configured via environment variables with the following format:

button_cmd_N_name=<button label>
button_cmd_N=<command to run>

Where N is the mapping number starting from 0. For example:

button_cmd_0_name=vol_down
button_cmd_0=fastboot usb 0

This will cause the device to enter fastboot mode if volume down is held
during boot.

After we enter the cli loop the button commands are no longer valid,
this allows the buttons to additionally be used for navigating a boot
menu.

efi_loader: split efi_init_obj_list() into two stages

In the next commit, CONFIG_EFI_SETUP_EARLY will become mandated
in order to support dynamic enumeration of efi_disk objects.

This can, however, be problematic particularly in case of file-based
variable storage (efi_variable.c, default).
Non-volatile variables are to be restored from EFI system partition
by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list()
is called in board_init_r(), we don't know yet what disk devices
we have since none of device probing commands (say, scsi rescan) has not
been executed at that stage.

So in this commit, a preparatory change is made; efi_init_obj_list() is
broken into the two functions;
* efi_init_early(), and
* new efi_init_obj_list()

Only efi_init_early() will be called in board_init_r(), which allows
us to execute any of device probing commands, either though "preboot"
variable or normal command line, before calling efi_init_obj_list() which
is to be invoked at the first execution of an efi-related command
(or at efi_launch_capsules()) as used to be.

efi_loader: capsule: add capsule_on_disk support

Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

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.

Make sure that argv[] argument pointers are not modified.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
...

Move CONFIG_UPDATE_TFTP code after CONFIG_PREBOOT

The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env

boot: add support for button commands

With the relatively new button API in U-Boot, it's now much easier to
model the common usecase of mapping arbitrary actions to different
buttons during boot - for example entering fastboot mode, setting some
additional kernel cmdline arguments, or booting with a custom recovery
ramdisk, to name a few.

Historically, this functionality has been implemented in board code,
making it fixed for a given U-Boot binary and requiring the code be
duplicated and modified for every board.

Implement a generic abstraction to run an arbitrary command during boot
when a specific button is pressed. The button -> command mapping is
configured via environment variables with the following format:

button_cmd_N_name=<button label>
button_cmd_N=<command to run>

Where N is the mapping number starting from 0. For example:

button_cmd_0_name=vol_down
button_cmd_0=fastboot usb 0

This will cause the device to enter fastboot mode if volume down is held
during boot.

After we enter the cli loop the button commands are no longer valid,
this allows the buttons to additionally be used for navigating a boot
menu.

binman replace -i flash.bin -f fit.fit fit

to:
binman sign -i flash.bin -k privatekey -a sha256,rsa4096 -f fit.fit fit

and to this one if it's need to be extracted, signed with key and put it

efi_loader: split efi_init_obj_list() into two stages

In the next commit, CONFIG_EFI_SETUP_EARLY will become mandated
in order to support dynamic enumeration of efi_disk objects.

This can, however, be problematic particularly in case of file-based
variable storage (efi_variable.c, default).
Non-volatile variables are to be restored from EFI system partition
by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list()
is called in board_init_r(), we don't know yet what disk devices
we have since none of device probing commands (say, scsi rescan) has not
been executed at that stage.

So in this commit, a preparatory change is made; efi_init_obj_list() is
broken into the two functions;
* efi_init_early(), and
* new efi_init_obj_list()

Only efi_init_early() will be called in board_init_r(), which allows
us to execute any of device probing commands, either though "preboot"
variable or normal command line, before calling efi_init_obj_list() which
is to be invoked at the first execution of an efi-related command
(or at efi_launch_capsules()) as used to be.

efi_loader: capsule: add capsule_on_disk support

Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

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.

Make sure that argv[] argument pointers are not modified.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
...

Move CONFIG_UPDATE_TFTP code after CONFIG_PREBOOT

The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env
