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.

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.

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

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

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.

spl: Remake SPL elf from bin

2026-03-13T19:21:52+00:00

On Xilinx MB-V there is a need to use ELF file for SPL which is placed
in BRAM (Block RAM) because tools for placing code to bitstream requires to
use ELF. That's why introduce SPL_REMAKE_ELF similar to REMAKE_ELF option
as was originally done by commit f4dc714aaa2d ("arm64: Turn u-boot.bin back
into an ELF file after relocate-rela").

There is already generic and simple linker script (arch/u-boot-elf.lds)
which can be also used without any modification.

spl: spi: fix loss of spl_load() error on soft reset

2026-03-13T19:21:46+00:00

When CONFIG_SPI_FLASH_SOFT_RESET is enabled, spi_nor_remove() is called
after spl_load() to switch the flash back to legacy SPI mode. However,
the return value of spi_nor_remove() unconditionally overwrites the
return value of spl_load(), discarding any load error.

Fix this by preserving the spl_load() error and only propagating the
spi_nor_remove() error as a fallback. Also log a message when
spi_nor_remove() fails, since in the case where spl_load() already
failed its error would otherwise be silently discarded.

common: spl: spl_dfu.c: Fix warning associated with PCI subclass_code

2026-03-12T08:59:33+00:00

The subclass_code member of the pci_ep_header structure is a 1-byte
field. The macro PCI_CLASS_MEMORY_RAM is a concetation of baseclass_code
and subclass_code as follows:
	PCI_BASE_CLASS_MEMORY: 0x05
	Subclass Code for RAM: 0x00
	PCI_CLASS_MEMORY_RAM:  0x0500
Hence, instead of extracting it via an implicity type conversion from int
to u8 which throws a warning, explicitly mask the bits to extract the
subclass_code.
