[Cbe-oss-dev] [RFC,PATCH 1/1] Allow PCAB to boot Linux 2.6.19

[Jean-Christophe Dubois]

SLOF on FACB/PCAB/CAB still has a quite mixed up device tree. The latest patch 
for 2.6.19 will not allow linux to boot on the PCAB as it will try to access 
the Axon MPIC with the ioremap method (instead of the DCR method) but it is 
then missing the 16 bytes striding info to go with it.

This patch allow the PCAB to boot 2.6.19 with Arnd patches from November 11th.

Note that unfortunately the MPIC controller info is present twice in the 
actual PCAB device tree. Therefore the MPIC is initialized twice. Once with 
the ioremap method and once with the DCR method. It is obviously not really 
the best thing.

A cleaner method would be to update SLOF on FCAB/PCAB/CAB so that it is at the 
same level as the Malta blade but we are not here yet.

Also this patch doesn't allow yet the ethernet driver to work on xCAB for 
2.6.19.
