Since Android 10, we are required to use a "dtbo" partition which
includes the various device-tree overlays [1].
It's also possible to provide a "dtb" partition.
This is supported via the "abootimg" command.
On Yukawa, the assumption is that we have only a "dtbo" partition, which
includes all board dtbs and their dtbos [2]

Implement A/B slot selection using the U-Boot ab_select command.
Keep support for non A/B.
Not: We need to redefine the recovery partition label, as RecoveryOS
is included in the boot image for A/B systems [1]

AVB (Android Verified Boot) is well supported in U-Boot already.
Add support for it in meson64_android.
This is controlled by the "force_avb" environment variable and the
CONFIG_CMD_AVB option.

Whenever we test for boot-fastboot in the BCB, it means that Android
wants us to boot into recovery with a special mode (fastbootd).
Force reboot into recovery in that case.
Note: we don't erase the bcb on purpose here: recoveryOS needs to read
the BCB as well to know if it boots into regular recovery mode or
fastbootd mode.

Right now meson64_android does not know how to boot into Android
Recovery: it simply falls back to "fastboot" mode in the bootloader.
Implement the boot to recovery.
While at it, use the standard BCB way instead of a sm for consistency.

As of today, we use a "vendor specific" secure monitor call for the
reboot reason (sm).
We should not need this. Android uses the BCB (Bootloader Control Block)
to communicate with the bootloader.
Implement "reboot into bootloader" using the standard BCB way instead of
using sm calls.

The console bootargs are already set from the kernel commandline.
On Android, this is done in yukawa at [1]
Don't set it in the bootloader since it's overridden by the kernel anyways.

To display the bootup logo, we read the gpt and assume that the
partition with index "2" will be the "logo" partition.
This might not always be the case, and it's very error-prone.
Load the logo partition by label instead of by index.

To boot Android, we read the gpt and assume that the partition with
index "1" will be the "boot" partition.
This might not always be the case, as there are no requirements from
Android on the partition order.
However, Android does seem to use the "boot" label quite a lot on their
public documentation [1]

This converts the following to Kconfig:
CONFIG_SYS_MMC_ENV_DEV
CONFIG_SYS_MMC_ENV_PART
Note that with this conversion we now have consistent behavior with
respect to ensuring that we have always selected the correct MMC
device and hardware partition.

- In ARMv8 NXP Layerscape platforms we also need to make use of
CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so.
- On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define
to 0.
- Add Kconfig entry for ENV_ADDR.
- Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it.
- Add ENV_xxx_REDUND options that depend on their primary option and
SYS_REDUNDAND_ENVIRONMENT
- On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
for the pre-main-U-Boot environment location.
- On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
rather it being non-zero, as it will now be zero by default.
- Rework the env_offset absolute in env/embedded.o to not use
CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
ENV_IS_IN_FLASH.
- Migrate all platforms.
