looking for documentation on porting Linux to PowerPC platforms

[Abraham vd Merwe]

Hi!

Is there a document somewhere describing the basics about the PowerPC
platform and Linux, i.e.

a) how to boot linux (can I just branch to the the address where I loaded t
he
image into ram or do I need to setup registers / data structures beforehand?)

b) where/what do I change if I want to add a "sub" architecture?

I've got a ICP-PPC PowerPC backplane type system here which I want to get
Linux on. It has the MPC8240 CPU on it which from what I read is pretty much
the same as the 8260, 8245, etc. (they're all based on the 603e core right?)

Now, if I select "8xx" in menuconfig, I get another selection of machine
types (RPX-Lite, RPX-Classic, etc.). Obviously I need to own my own machine
type here, but how do I do that. Also, how does these machine types differ?
Just different peripherals? Do they have anything in common (e.g. uart).
