I have ramdisk pcore-680 working reasonaly well and
an almost working Powerk2 port, if anyone else is intrested.
I (and my company trapeze networks) am happy to push all of code the back.

The IBMPowerk2 has support for the cpc710 daul PCI/memory/flash
controller (but I only coded it for one host bridge) and is
an ugly merge of walnut/sandpoint - I would rewrite much of
this again if anyone was serious about using it. This boots
via ftp from IBM's K2 elf bootloader

The Force PowerCore cpci680 is based on the sandpoint port and is
realitively clean. It supports the MPC107 northbridge with a
WINBOND isa bridge providing 8259 PIC cascaded into the OPENPIC
of the 107. This boots from flash or IBMminidrive (ide) or ftp
from Force's bootloader.

In doing these ports, I notice much of the powerpc varients do not
reuse code. Is anyone looking into making all of powerpc more sharable
between the varients? Even the source layout could be improved by
having the varients all under "powerpc" rather then peers, IMHO.
