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.
