That's going back quite a few years... and yes, it wasn't trivial.  How
it used to be done was with a boot loader called 'milo' which read the
kernel out of flash - you had to program it and the kernel using 'afu'
via the debugger.

Looking at the various scripts I have around, the other way I did it was
using Angel (and presumably armsd).  I have this .angelrc file:

device /dev/ttyS3
options "9600 8N1"
baud 115200
base 0x00008000
entry 0x00008000
#otherfile ramdisk_img.gz
#otherbase 0xc0800000
r0 0x00
r1 21
exec .start-minicom

and .start-minicom is:
#!/bin/sh
exec ~/bin/start-minicom int

Not sure if any of this helps, but might provide some hints.
