When RK3308 boards run SPL from eMMC and fail to load FIT from eMMC due to it being missing or checksum validation fails there can be a fallback to read FIT from SD-card. However, without proper pinctrl configuration reading FIT from SD-card may fail: U-Boot SPL 2024.04-rc4 (Mar 16 2024 - 12:36:12 +0000) Trying to boot from MMC2 mmc_load_image_raw_sector: mmc block read error Trying to boot from MMC1 Card did not respond to voltage select! : -110 mmc_init: -95, time 12 spl: mmc init failed with error: -95 Trying to boot from MMC2 mmc_load_image_raw_sector: mmc block read error SPL: failed to boot from all boot devices (err=-6) ### ERROR ### Please RESET the board ### Fix this by tagging related emmc and sdmmc pinctrl nodes with bootph props.

2024-04-26rockchip: spl: Cache boot source id for later useJonas Karlman
Rockchip BROM writes a boot source id at CFG_IRAM_BASE + 0x10, this id indicates from what storage media TPL/SPL was loaded from. SPL uses this id to determine what device "same-as-spl" represent when determining from where FIT should be loaded. This works as long as the boot_devices array contain a matching id <-> node path entry. However, SPL typically load a small part of TF-A into SRAM and on RK3399 this overwrites the CFG_IRAM_BASE + 0x10 addr used for boot source id. For affected devices the u-boot,spl-boot-device would not be set when booting from SPI flash and the flash@0 node was not explicitly listed in the u-boot,spl-boot-order prop. Here boot source id is 3 before FIT images is loaded, and 0 after: U-Boot SPL 2024.04-rc4 (Mar 15 2024 - 17:26:19 +0000) board_spl_was_booted_from: brom_bootdevice_id 3 maps to '/spi@ff1d0000/flash@0' Trying to boot from SPI ## Checking hash(es) for config config-1 ...

Not many and nothing really exciting this time: there are more patches in fly, but they are not ready yet. I will also send some DT updates and new board defconfig files later, once they have seen the list. I am aware of the USB rebasing repo efforts, but would like to see how this plays out, also we have one compatibility issue that I painstakingly work around in the U-Boot tree for the last three years or so. So for now I stick to the previous approach. So now just some easy changes: support for USB peripheral mode on the Allwinner F1C100s, T113-s3 SPI boot support, and some SPL cleanup patches. The branch passed the gitlab CI run, and brief boot testing on some boards didn't turn up any issues.
