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).
