You are sensible :-)

We have a boot loader, the pbsdboot for NetBSD/hpcmips. Please
see syssrc/sys/arch/hpcmips/stand/pbsdboot. You may write CPU depend
part sh.c like pbsdboot/mips.c.

Also, LinuxSH3 has a boot loader, which is an application program on 
the Windows CE. You can get source code from:

You may feel that LinuxCE's loader is different from the pbsdboot,
but they have same structure.
