Actually, the linuxppc-2.4 support is incomplete, there's no TSEC/FEC
driver or other on-chip peripheral drivers in that tree to make it
really useful. You could just use a PCI network card to nfsroot a
filesystem and get started, though.
http://www.metrowerks.com/MW/Develop/Embedded/Linux/BSP.htm has
an 8560ADS BSP for download...it probably has some drivers for
on-chip peripherals included.
BTW, you'll need the following patch to linuxppc-2.4 to fix outbound
PCI mem cycles:
