Arnold is a product of Keith & Koep GmbH
http://www.keith-koep.com/
They have ported Linux 2.2.9 to Arnold, and does provide
a mechanism to program Linux kernel and ramdisk to Flash.
I've ported Linux 2.2.14 to Arnold, and trying their flash
programming mechanism. ( init/flash.c )
Their approach is to first download the kernel to Arnold,
and then program the kernel into flash while kernel starts up.

I think TFTP boot would be easier to implement. :)

I don't understand the idea of ROM SIMM.
Could you compare it with the original flash ROM on Brutus?
Thank you.
