The format that your Linux kernel builds, and more particularly the
format used by the applications, don't matter to RedBoot at all.

All you need to do to boot Linux is convert the COFF image to a raw
binary file.  Then just tell RedBoot that this is the case when you
load it.  For example:
  RedBoot> load -r -b 0x100000 linux_kernel.bin
  RedBoot> exec

The Linux kernel itself will take care of your applications.
