ARM_TRUSTED_FIRMWARE_SITE is currently pointing to the deprecated
ARM-software github read-only mirror[0] which is no longer publishing
new tags. They do have a newer github mirror under the TrustedFirmware-A
organization[1] which continues to receive tag updates we could use
however because of the way github generates tarballs changing the SITE
to point to TrustedFormware-A changes the pre-calculated hash values
for every version for everyone.
Without much way around changing all hash values if we want these latest
tags, lets drop the github mirrors and move to the official git
source[2] so we can download real tarballs which shouldn't change even
if the ARM_TRUSTED_FIRMWARE_SITE moves again and hopefully preventing
this from ever happening again.

- v2.6 changes to FIP instead of SSBL boot.
- This requires switching to u-boot.bin in U-Boot, and using that
instead of .stm32 in ATF.
- fiptool expects dtb to be split off from u-boot.bin, so need custom
u-boot-nodtb.bin in addition to u-boot.dtb.
Caveat: this is perhaps not really obligatory, but the ATF
documentation explains it like that.
- The partition must be named fip (while it must be named ssbl for
SSBL boot).
- Since the partition name is set in the common template, all
defconfigs using that template must be bumped in a single commit
- ATF now produces both fip.bin and <boardname>.stm32, so fip.bin has
been added to the configs
- While we're at it, add the structuring comments to

The regex was a bit too strict in which characters it allowed. Thus,
if e.g. a file name appears in the
BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES string, it no
longer matches, and we end up with an empty ATF_VARIABLES. This makes
the subsequent grep fail, and the post-image.sh script fails without
any error message (thanks to the -e option).
Simplify the regex to match everything except the closing quotation
mark. Note that Kconfig doesn't allow quotation marks at all inside a
string (even escaped ones), so this regular expression is always OK.

The post-image.sh script is used in several STM32MP157-based board
configs. It had hardcoded device tree file names for the supported
boards which were used for matching the expected TF-A binary name.
Replace this mechanism with a pair of grep and sed that build the TF-A
binary name from the device tree file name. For example, if
BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES contained
DTB_FILE_NAME=stm32mp157c-dk2.dtb, the appropriate TF-A file would be
named tf-a-stm32mp157c-dk2.stm32.
Since the Bash Here Strings are removed with this change, I took the
opportunity to remove the only other non-POSIX command, "local", and
then I was able to change the shebang to plain /bin/sh, with -eu for
simpler error handling.

Newer versions of the kernel generate device trees that are not

must be changed.
The commit 2e499dcff3ef ("Add possibility to use custom kernel load address")
adds the possibility to override the default (0x08008000) kernel load
address.
This also required changes to the stm32f429_disco_defconfig and

I took that one.
After Linux boots, /dev/fb0 will be accessible. You can control the

following commands:
~ # echo 0 0 > /sys/class/graphics/fb0/pan
~ # echo 255 >/sys/class/backlight/40016c00.dsi.0/brightness
The brightness ranges from 0 to 255, as you can see running the
command:
~ # cat /sys/class/backlight/40016c00.dsi.0/max_brightness

The stm32mp157 images successfully boot only once. Subsequent boot
attempts fail to reach U-Boot. The root cause turns out to be in U-Boot
corruption during the first boot. The stm32mp1 U-Boot stores its
environment at the end of GPT partition named 'ssbl' since v2020.10-rc2.
However Buildroot genimage template for stm32mp157 boards creates 'ssbl'
partition w/o extra space for U-Boot primary and redundant environments.
This patch explicitly specifies 'ssbl' partition size that should be
enough for both u-boot.stm32 image (~1M) and both environments (16K).

As described by [1], the kernel generated by the configuration for the
STM32f469 Discovery board is buggy. Using a newer kernel, as suggested
by [1], increases the dtb and Kernel image size. In particular, the
5.12 version of the kernel generates a dtb and a kernel image whose sum
exceeds the 2 MByte of the flash module.
So I decided to replace the afboot-stm32 bootloader in the flash with
U-boot to easily boot the system from sdcard without having to worry
about the size of dtb, kernel and rootfs generated by the configuration.
This solution allows you to fix the kernel boot issue and makes it
possible to use its future versions.

This commit changes the stm32mp1 configurations to use the TF-A ->
U-Boot boot flow (called "trusted boot flow" by ST) instead of the
U-Boot SPL -> U-Boot boot flow. ST recommands this trusted boot, and
it's also the only one that allows to use the STM32 Cube Programmer
for reflashing devices.
As part of this, the genimage configuration file is now generated, as
it contains some file names that depend on the platform. Removing
partition-type from genimage.cfg is mandatory, since it would cause a
hybrid MBR partition table to be created, which itself would prevent
ATF from finding the ssbl parition.
