Platform specific BootROM may use its own image type for loading SPL or main U-Boot binary. In some cases it makes sense to not use BootROM supplied code for booting main U-Boot binary but rather to use U-Boot SPL to load main U-Boot binary, e.g. when U-Boot SPL can load main U-Boot binary faster than BootROM. In this case it is required for platform board code to parse and load U-Boot in BootROM specific image type.
This change adds support for parsing platform / board / BootROM specific image types via weak function spl_parse_board_header() which is called before marking boot image as a raw.
