Booting Integrator/AP with ARM920T

I have this Integrator/AP development board here in my office:

Does anyone beside me *ever* try to actually boot a recent kernel
on this thing?

How do you do it? Do I need patched U-boots etc, or can I just load
a Z-record image of vmlinux into RAM over the serial console?

Needless to say, ARM Ltd. has deleted the web pages for official
support of this thing as far as I can see. I was going to try out a
few patches affecting mach-integrator...

Yours,
Linus Walleij

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.
