SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

SPL: Move the omap SPL framework to common/spl Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.

spl: change return values of spl_*_load_image() Make spl_*_load_image() functions return a value instead of hanging if a problem is encountered. This enables main spl code to make the decision whether to hang or not, thus preparing it to support alternative boot devices. Some boot devices (namely nand and spi) do not hang on error. Instead, they return normally and SPL proceeds to boot the contents of the load address. This is considered a bug and is rectified by hanging on error for these devices as well.

spl: mmc: support uboot image offset on main partition On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC hardware boot partitions. When there are no boot partitions (i.e. SD card) the ROM skips the first sector that usually contains the (logical) partition table. Since the generated .kwb image contains the main U-Boot image in a fixed location (0x140 sectors by default), we end up with the main U-Boot image in offset of 1 sector. The current workaround is to manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to compensate for that. This patch uses the run-time detected boot partition to determine the right offset of the main U-Boot partition. The generated .kwb image is now compatible with both eMMC boot partition, and SD card main data partition.

spl: Weed out CONFIG_SYS_TEXT_BASE usage The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location is available and can be corrupted by loading ie. uImage or fitImage headers there. Sometimes it could be beneficial to load the headers elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we still want to parse the image headers in some local onchip memory to ie. extract firmware from that image. Add the possibility to override the location where the headers get loaded by introducing new function, spl_get_load_buffer() which takes two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the data that are to be loaded there -- and returns a valid buffer address or hangs the system. The default behavior is the same as before, add the offset to CONFIG_SYS_TEXT_BASE and return that address. User can override the weak spl_get_load_buffer() function though.

spl: Make image loader infrastructure more universal The current U-Boot SPL image loader infrastructure is very powerful, able to initialize and load from a variety of boot media however it is strongly geared towards loading specific types of images in a very specific way. To address the need being able to use this infrastructure to load arbitrary image files go ahead and refactor it as follows: - Refactor existing spl_mmc_load_image function into superset function, accepting additional arguments such as filenames and media load offset (same concept can also be applied toother spl_XXX_load_image functions) - Extend the loader function to "remember" their peripheral initialization status so that the init is only done once during the boot process, - Extend the FIT image loading function to allow skipping the parsing/ processing of the FIT contents (so that this can be done separately in a more customized fashion) - Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function, invoking the newly refactored superset functions in a way to maintain compatibility with the existing behavior This refactoring initially covers MMC/SD card loading (RAW and FS-based).

spl: mmc: support uboot image offset on main partition On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC hardware boot partitions. When there are no boot partitions (i.e. SD card) the ROM skips the first sector that usually contains the (logical) partition table. Since the generated .kwb image contains the main U-Boot image in a fixed location (0x140 sectors by default), we end up with the main U-Boot image in offset of 1 sector. The current workaround is to manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to compensate for that. This patch uses the run-time detected boot partition to determine the right offset of the main U-Boot partition. The generated .kwb image is now compatible with both eMMC boot partition, and SD card main data partition.

spl: spl_mmc: fix getting raw_sect when boot from emmc boot partition On i.MX8, when booting from eMMC boot partition, the whole flash.bin is stored in boot partition, however SPL switches to user partition during the init of mmc driver: spl_mmc_load() -> mmc_init() Then it tries to load the container image in spl_mmc_get_uboot_raw_sector(), but here it reads the data from user partition and the header is not recognized as a valid header. So we move spl_mmc_get_uboot_raw_sector after eMMC partition switch to address this issue.

spl: mmc: support uboot image offset on main partition On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC hardware boot partitions. When there are no boot partitions (i.e. SD card) the ROM skips the first sector that usually contains the (logical) partition table. Since the generated .kwb image contains the main U-Boot image in a fixed location (0x140 sectors by default), we end up with the main U-Boot image in offset of 1 sector. The current workaround is to manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to compensate for that. This patch uses the run-time detected boot partition to determine the right offset of the main U-Boot partition. The generated .kwb image is now compatible with both eMMC boot partition, and SD card main data partition.
