In order to maintain the chain of trust, each stage of the boot process
will first authenticate each binary it loads before continuing. To
extend this to the kernal and its dtbs we can package the kernal and
its dtbs into another fitImage for Uboot to authenticate and extend the
chain of trust all the way to the kernel.
When 'boot_fit' is set, indicating we're using the secure bootflow, look
for and authenticate the kernel's fitImage.

Texas Instruments has begun enabling security settings on the SoCs it
produces to instruct ROM and TIFS to begin protecting the Security
Management Subsystem (SMS) from other binaries we load into the chip by
default.
One way ROM and TIFS do this is by enabling firewalls to protect the
OCSRAM and HSM RAM regions they're using during bootup.
The HSM RAM the wakeup SPL is in is firewalled by TIFS to protect
itself from the main domain applications. This means the 'bootindex'
value in HSM RAM, left by ROM to indicate if we're using the primary
or secondary boot-method, must be moved to OCSRAM (that TIFS has open
for us) before we make the jump to the main domain so the main domain's
bootloaders can keep access to this information.

One way ROM does this is by enabling firewalls to protect the OCSRAM

time to disable the OCSRAM firewall region) will we have write access to

This means we will need to move the stack & heap from OCSRAM to HSM RAM
and reduce the size of BSS and the SPL to allow it to fit properly.

The boot mode detection assumes that BOOT_DEVICE_MMC2 should always
result in MMCSD_MODE_FS, but MMCSD_MODE_RAW is also a valid option for
this port.
The current logic also avoids looking at the bootmode pin strapping,
which should be the primary means of determining whether a device is
being booted in MMCSD_MODE_EMMCBOOT mode.
Switch around the logic to check the boot mode to determine whether the
eMMC boot mode is expected or MMC/SD boot mode. From there we can look
at the boot mode config if in MMC/SD boot mode to determine whether to
attempt RAW or FS based booting.
This change allows U-Boot to also be successfully booted from RAW
offsets in addition to from a filesystem.

To quote the author:
Update in U-Boot env mmc backend with several cosmetic changes or
corrections and 2 new features:
1/ CONFIG_ENV_MMC_USE_DT = no more use CONFIG_ENV_OFFSET
in the mmc ENV backend when this config is activated.
Requested by the STM32MP STMicroelectronics boards which activate
several ENV_IS_IN_XXX; the value of CONFIG_ENV_OFFSET is invalid for
SD-Card / eMMC boot; this offset should only used in SPIFlash backend
(sf.c) for SPI-NOR boot.
If this offset is used on mmc backend, when partition name in GPT is
not aligned with U-Boot DT: "u-boot,mmc-env-partition", the behavior
is difficult to debug: a partition is corrupted on 'env save' command.
2/ selects the GPT env partition by the "u-boot-env" type GUID introduced
by the commit c0364ce1c6 ("doc/README.gpt: define partition
type GUID for U-Boot environment")
This feature can also avoid issue when 'u-boot-env' partition name
change in GPT partitioning but not in the U-Boot DT with
"u-boot,mmc-env-partition"

For some newer SoCs like RK3568, the Rockchip has not released
any DDR drivers yet so idbloader needs to create manually using
DDR binaries offered by rkbin. This indeed no requirement to

If we mark TPL disabled and mark BINMAN enabled by default then
there would be an issue of binman_init failure during board
relocation. This is true as binman failed to find the top-level
node like u-boot-tpl here.
Here is the boot issue observed in Radxa-CM3 RK3566 board,
