405GPr support in linux2.4.18

[Laurent Mohin]

Hello all,

I'm designing a board with 405GP processor. I'm now trying to have it
working with a 405GPr version.
I've started to configure it working in legacy mode and made the necessary
changes in PPCBoot.

Once downloaded, my kernel hung in early_init function when it called the
memset_io to zero the BSS. Using a BDI2000 debugger, I saw that I've
reached the bad_page_fault function.

The only difference I know between 405GP and 405GPr in legacy mode is data
cache size. How does the kernel manage it?

I'm currently using kernel 2.4.18 from Montavista.

Any help is welcome,

Laurent
