2024-06-17spl: Introduce SoC specific init functionLukas Funke
Some architectures use spl_board_init() in their SoC specific implementation. Board developers should be able to add board specific implementation via spl_board_init(). Hence, introduce a spl_soc_init() method which is called right before spl_board_init() for SoC specific implementation.

2023-11-16spl: Only support bl_len when we have toSean Anderson
Aligning addresses and sizes causes overhead which is unnecessary when we are not loading from block devices. Remove bl_len when it is not needed. For example, on iot2050 we save 144 bytes with this patch (once the rest of this series is applied): add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-144 (-144) Function old new delta spl_load_simple_fit 920 904 -16 load_simple_fit 496 444 -52 spl_spi_load_image 384 308 -76 Total: Before=87431, After=87287, chg -0.16% We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still need to be able to compile it for things like mmc_load_image_raw_sector, even if that function will not be used.

2023-11-16spl: Remove filename from spl_load_infoSean Anderson
For filesystems, filename serves the same purpose as priv. However, spl_load_fit_image also uses it to determine whether to use a DMA-aligned buffer. This is beneficial for FAT, which uses a bounce-buffer if the destination is not DMA-aligned. However, this is unnecessary now that filesystems set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can remove filename entirely. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2023-11-16spl: Refactor spl_load_info->read to use units of bytesSean Anderson
Simplify things a bit for callers of spl_load_info->read by refactoring it to use units of bytes instead of bl_len. This generally simplifies the logic, as MMC is the only loader which actually works in sectors. It will also allow further refactoring to remove the special-case handling of filename. spl_load_legacy_img already works in units of bytes (oops) so it doesn't need to be changed.

2023-10-17test: spl: Add a test for the SPI load methodSean Anderson
Add test for the SPI load method. This one is pretty straightforward. We can't enable FIT_EXTERNAL with LOAD_FIT_FULL because spl_spi_load_image doesn't know the total image size and has to guess from fdt_totalsize.

2023-10-17spl: mmc: Introduce proper layering for spl_mmc_get_uboot_raw_sector()Marek Vasut
Introduce two new weak functions, arch_spl_mmc_get_uboot_raw_sector() and board_spl_mmc_get_uboot_raw_sector(), each of which can be overridden at a matching level, that is arch/ and board/ , in addition to the existing weak function spl_mmc_get_uboot_raw_sector(). This way, architecture code can define a default architecture specific implementation of arch_spl_mmc_get_uboot_raw_sector(), while the board code can override that using board_spl_mmc_get_uboot_raw_sector() which takes precedence over the architecture code. In some sort of unlikely special case where code has to take precedence over board code too, the spl_mmc_get_uboot_raw_sector() is still left out to be a weak function, but it should be unlikely that this is ever needed to be overridden.

2023-09-30Convert CFG_SYS_UBOOT_START to KconfigJesse Taube
Commit 65cc0e2a65d2 ("global: Move remaining CONFIG_SYS_* to CFG_SYS_*") renamed CONFIG_SYS_UBOOT_START to CFG_SYS_UBOOT_START. Unfortunately, this meant that the value was no longer available to the Makefile. This caused imxrt to fail to boot. All the other boards that used this variable were unaffected because they were using the default value which is CONFIG_TEXT_BASE.
