Power PC G4 - KeyLargo and U2 drivers
Hi,
I'm trying to port my RTOS to apple commercial
board "Power Mac G4 - Xserver - Cluster node".
They are using two custom made ICs which are
U2 bridge and memory controller, KeyLargo
IO and disk controller. KeyLargo intern has
MPIC cell as interrupt controller.
I'm very new to open Firmware. Now, I need to
find out/write drivers for those two chips to
my operating systems.
Is there any driver's available that I can reuse?
Since, I don't have a spec for both chips, how
do I go about doing this? Would appreciate any
pointers.
Thanks,
Sakthi
