bootm: refactor image detection and os load steps
Created a bootm_start() that handles the parsing and detection of all the images that will be used by the bootm command (OS, ramdisk, fdt). As part of this we now tract all the relevant image offsets in the bootm_headers_t struct. This will allow us to have all the needed state for future sub-commands and lets us reduce a bit of arch specific code on SPARC. Created a bootm_load_os() that deals with decompression and loading the OS image. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
