Hi all,
We currently make use of CMD_BOOTI and CMD_BOOTZ in the SPL boot flow in
falcon mode, this isn't correct since all CMD_* configs are only meant
for U-Boot proper and not the SPL.
Therefore this patch set adds new LIB_BOOT[IMZ] configs that allow for
more granular selection of their respective compilation targets.
Additionally, this also allows us to more easily disable support for
raw images from secure falcon mode (SPL_OS_BOOT_SECURE) by doing the
following:
config LIB_SPL_BOOTI
...
depends on SPL_OS_BOOT && !SPL_OS_BOOT_SECURE
...

This patch documents the newly added SPL_OS_BOOT_SECURE option that
enables authenticated boot in falcon mode.
The document provides steps for using secure falcon mode on ARM64 taking
TI's AM62x EVM as an example.

With CONFIG_SPL_OS_BOOT enabled, U-Boot checks for the return value of
spl_start_uboot to select between falcon or the regular boot flow. Where
a return value of 0 means 'boot to linux'.
This patch overrides the weak definition form common/spl/spl.c to allow
K3 devices to use falcon mode with SPL_OS_BOOT_SECURE enabled for the
A-Core SPL.

Add CMD_SPL to list of configs implied by TI_COMMON_CMD_OPTIONS. This
allows the use of 'spl export'[1] command for preparing a device-tree

Falcon mode was disabled for TI_SECURE_DEVICE at commit e95b9b4437bc
("ti_armv7_common: Disable Falcon Mode on HS devices") for older 32-bit
HS devices and but can now be enabled with the addition of
OS_BOOT_SECURE.
For secure boot, the kernel with x509 headers can be packaged in a fit
container (fitImage) signed with TIFS keys for authentication.

In the existing behaviour, CMD_BOOTZ is not enabled by default which
means zimage.o is not compiled in the SPL in falcon mode unless
explicitly enabled. This changes now as SPL_BOOTZ is default y for
falcon users which leads to larger SPL size with zimage.o being present.
This patch modifies the defconfigs that used falcon mode but don't
require zimage support.

Using CMD_* configs from spl doesn't make logical sense. Therefore
this patch replaces the checks for CMD_BOOTx with newly added library
symbols LIB_BOOT[IMZ] and SPL_LIB_BOOT[IMZ] which are enabled by their
respective CMD_* or SPL_* counterparts.
On platforms with non-secure falcon mode, SPL_BOOTZ is enabled by
default for 32-bit ARM systems and SPL_BOOTI is enabled by default for
64-bit ARM and RISCV.
The respective C files (image.c/zimage.c) are compiled based on library
symbols $(PHASE_)LIB_BOOTx instead which are in turn selected by both
CMD_BOOTx and SPL_BOOTx as required.

This series converts the extension board framework to use UCLASS as

I can't test the imx8 extension scan enabled by the

The extension_overlay_cmd environment variable approach is specific to
the U-Boot extension_board command, while other boot flows (pxe_utils,
bootstd) handle overlay loading differently.
Move the extension_overlay_cmd execution out of the core extension
framework to the command level. This decouples the framework from
command-specific behavior and prepares for future extension support
in other boot flows.

The CAPE_EEPROM_BUS_NUM configuration option was incorrectly depending
on CMD_EXTENSION, which represents the extension board command. However,
the cape scan functionality can be built and used independently of the
command interface through the SUPPORT_EXTENSION_SCAN option.
Change the dependency from CMD_EXTENSION to SUPPORT_EXTENSION_SCAN to
properly reflect that the I2C bus configuration is needed for the cape
scan function itself, not specifically for the command.

The free running mode is 0 at bit offset 1. User mode is 1 at bit offset
1. Currently, free running mode is 1 at offset 0, which is already the
case thanks to TIME_EN.
So, this essentially does not change the actual value written to the

= 0b1, and will become 0x1 | (0 << 1) = 0b1.

eMMC erase and write support on RK3528 is somewhat unreliable, sometime
e.g. mmc erase and write commands will fail with an error.
Use the delay line lock value for half card clock cycle, DLL_LOCK_VALUE,
to set a manual xx_TAP_VALUE to fix the unreliable eMMC support.
This is only enabled for RK3528, remaining SoCs still use the automatic
tap value, (DLL_LOCK_VALUE * 2) % 256, same value we configure manually
for RK3528.

The only difference with the implementation in spl_common.c is that we
check whether the timer has already been enabled. Considering this is
running in SPL, the first stage on RK3036, I feel like it's guaranteed
to not be enabled by default. No public TRM though and I don't have
access to an RK3036 device so take this as a guess.
Size of SPL binary increases by 8B for evb-rk3036.

Boot devices are being probed when SPL boot order is determined. This
may delay boot slightly and can prevent booting from SPI Flash on boards
that use same pins for SPI Flash and eMMC due to pinctrl being applied
prior to booting.
Instead defer probe of the boot device until SPL try to load image from
the boot device by using uclass_find_device_by_of_offset() instead of
the get variant.

STIMER already being enabled. Experimentally, STIMER is not already

Anbernic RG353M is hardware compatible with RG353P. Only the form-factor
differs. So only one DTS is created for both machines with
"Anbernic RG353P" as default model. If a RG353M is detected, the model
should be overwritten with the correct name.
Actually, it's overwritten with "Anbernic" only making the process of
machine detection a little harder.
However, to determine the size of the string "Anbernic RG353M", it is
sizeof() which is used resulting in obtaining the size of the pointer
(which is 8 bytes on ARM64) not the size of the pointed string.
strlen() should be used instead.

Forcing all those symbols on means we cannot make the binary smaller or
with unnecessary features or drivers disabled. This is especially useful
for security, auditing and certification where less code built means
less to look at (and less surface attack) and less to patch, but also
for making binary images smaller which typically means faster boot.
It is possible to have boards without MMC, NAND or SPI flashes, without
anything on SPI or I2C buses, nothing to control over PWM or GPIO or for
which we have no interest in regulator control or serial output so make
it possible to remove all that if desired.
No intended change in default selected symbols.
