I fixed that here.
TheKconfig issue is really minor compared to the rest :-)

Yeah, and also, Pegasos II kernel shouldn't call all the chipset init call
which has been added.
Pegasos II chipset init is done by the OFW. OSs kernel shouldn't have to
touch it much.

I already patch a bit the kernel. However, enabling new Marvell code means
not booting anymore ATM.
I'm trying to find a way to patch the current source, without breaking
Katana & friends support.
The smartest could be to move all unneeded/board specific code somewhere
else (chipset init...) and to keep ony the minimal (only
platform_get_resource() realted stuff), in arch/ppc/syslib/mv64x60*
