One of the advantages of the MontaVista CDK is it's similarity among
all processors and boards supported.  Since you were successful with
StrongARM, PowerPC should be just as easy.

You mentioned in your first message this was a Motorola board.  What
is it?  If the LSP exists in the CDK, it should "just work" and be
documented how to do so.  If the LSP isn't in the CDK, you have
porting work ahead of you (and you are going to need lots more than
the documentation for the board :-).  Did you purchase a subscription
and are entitled to top quality Linux consulting support?  If so,
call them.

It's a Rev. C1 part, and a generic 860 (no 10/100 FEC, SAR, or
enhanced CPM features), so you should be OK.  Not many silicon bugs
left in that one.

Have fun!
