This file has code in three different categories: - Command processing - OS-specific boot code - Locating images and setting up to boot

Only the first category really belongs in a file called cmd_bootm.c.

Leave the command processing code where it is. Split out the OS-specific boot code into bootm_os.c. Split out the other code into bootm.c

Header files and extern declarations are tidied but otherwise no code changes are made, to make it easier to review.
