spl: Remove unused CONFIG_SPL_FRAMEWORK_BOARD_INIT_F option

2026-04-07T21:26:47+00:00

The option CONFIG_SPL_FRAMEWORK_BOARD_INIT_F enables a simple
board_init_f function in SPL. This however is never enabled, so remove
this function and option.

spl: env: Correct dependencies for SPL_SAVEENV and MMC

2026-04-07T17:32:39+00:00

The SPL_SAVEENV functionality, when working with an MMC device, can only
work with SPL_MMC_WRITE enabled. This however only works with SPL_MMC
also being enabled. Update the dependencies to show that if we have
enabled SPL_ENV_IS_IN_MMC then we select SPL_MMC_WRITE and make
SPL_ENV_IS_IN_MMC depends on SPL_MMC.

console: Prefer currently selected serial console as stdio device

2026-03-30T23:02:17+00:00

Adjust the scan for default console stdio device to prefer the
currently selected serial device. This is useful in combination
with CONFIG_SERIAL_PROBE_ALL=y, in which case the system would
instantiate all serial devices as stdio devices in the order in
which they are listed in control DT. The currently selected serial
device may not be the first device listed in DT, in which case the
current console_init_r() implementation unexpectedly switches to
another serial console after listing stderr using "Err:" line, and
just before showing U-Boot shell, which is not the desired behavior.

The scan now iterates over the entire list of stdio devices. If the
current iterator stdio device is the current serial device, or there
is no input or output stdio device assigned to the input or output
stream yet, then the current iterator stdio device is assigned to that
stream. This way, the first suitable stdio device is assigned to the
stream, but the current serial console stdio device can override that
assignment.

As a small optimization, if the current iterator stdio device is the
current serial device and both input and output streams as assigned,
then the loop can terminate, because the current serial device has a
chance to be used as a stdio device at this point.

SPL: Rework logic around SPL_BLK_FS (and SPL_NVME)

2026-03-30T21:02:27+00:00

As exposed by "make randconfig", we have an issue around SPL_BLK_FS.
This is functionally a library type symbol that should be selected when
required and select what it needs. Have SPL_BLK_FS select SPL_FS_LOADER
and then SPL_NVME will now correctly select SPL_FS_LOADER via
SPL_BLK_FS.

arm: relocate: Introduce data-only relocation mode

2026-03-27T19:29:31+00:00

Introduce new mode of relocation which relocates only data, not code.
This is mainly meant to relocate data to read-write portion of the RAM,
while the code remains in read-only portion of the RAM from which it is
allowed to execute. This split configuration is present on various secure
cores.

The result of the relocation is U-Boot running at its original address,
data relocated to the end of DRAM, but with added read-write area offset.
The U-Boot binary area is not reserved from the end of the DRAM in this
relocation mode, because U-Boot itself is not relocated.

Merge patch series "Introduce SQUASHFS support in SPL"

2026-03-26T17:04:41+00:00

Richard Genoud  says:

SquashFS has support in U-Boot, but not in SPL.

This series adds the possibility for the SPL to load files from SquashFS
partitions.
This is useful, for instance, when there's a SquashFS rootfs containing
U-Boot binary.

NB: falcon mode is not supported yet.

spl: mmc: support squashfs

spl_mmc_do_fs_boot supports now loading an image from squashfs.

Also, convert #if defined(CONFIG_SPL_xx) to if (CONFIG_IS_ENABLED(xx))

spl: add squashfs support

2026-03-26T17:04:28+00:00

Implement spl_load_image_sqfs() in spl code.

This will be used in MMC to read a file from a squashfs partition.

Also, loosen squashfs read checks on file size by not failing when a
bigger size than the actual file size is requested. (Just read the file)
This is needed for FIT loading, because the length is ALIGNed.

Merge patch series "led: remove legacy API"

2026-03-18T19:13:57+00:00

Quentin Schulz  says:

This migrates the last user of the legacy LED API, IMX233-OLinuXino and
net/bootp.c, to the modern LED framework.

I do have concern about being able to use BOOTP in SPL? In which case, I
should probably add an additional check on CONFIG_IS_ENABLED(LED) in
addition to IS_ENABLED(CONFIG_LED_BOOT)?

I haven't tested this as I do not own an IMX233-OLinuXino, so please
give this a try if you own this device.

Then, since there's no user left of this legacy API, it is entirely
removed.

led: remove legacy API

2026-03-18T19:07:36+00:00

No user of the legacy LED API anymore (except Sunxi with the PinePhone
but that is now a Sunxi-specific implementation), so let's remove
anything related.
