AM654 allows for booting from primary or backup boot media. Both media can be chosen individually based on switch settings. ROM looks for a valid image in primary boot media, if not found then looks in backup boot media. In order to pass this boot media information to boot loader, ROM stores a value at a particular address. Add support for reading this information and determining the boot media correctly.
