MVME 5100

Hi Everybody !

I am trying to run Linux on an MVME5100 board. I am using PReP-style booting and got the boot process and some of the kernel initialization running. But I am missing any knowledge of other PowerPC boards or machines, so that it is relativly hard to find out what exactly to change. So I have a question: The MVME5100 is missing all ISA stuff. Is the IRQ mapping (first 16 for the 8259 and the other 16 for the MPIC) still valid ?

Also I run in a problem: the indirect mechanism for generating PCI config cycles is set up correctly, but the board seems to hang when reading from the CONFIG_DATA address !!!???

I would more then appreciate any hints.

Might as well just use 16-31 and stick with the MPIC convention. If somebody else is using the 5100 with the IPMC761 then they will have ISA and will thank you many times for not changing things.

Make sure you have those Hawk registers covered with a BAT or PTEs. Notice the areas covered by BATs in the MACH_prep BAT setup case in arch/ppc/mm/init.c.
