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.

spl: Make UFS available for SPL builds

2026-03-12T08:30:44+00:00

Add minimal infrastructure to build SPL images with support for UFS
storage devices. This also pulls in SCSI support and charset functions,
which are dependencies of the UFS code.

With this, only a fixed offset is supported for loading the next image,
which should be specified in CONFIG_SPL_UFS_RAW_U_BOOT_SECTOR as the
number of 4096-byte sectors into the UFS block device.
