Tom,
I think that GRUB2 obsoletes significant portion of current psm/ code.
We shouldn't care about disk IO and UFS access via the OpenFirmware -
the GRUB loader does it for us and bring everything into the memory.
We do, however, need a terminal IO facility - it (as Joerg mentioned
earlier ) is very important during the initial phase of porting (good ol'
printf :) ).
Also can you post a list of files under usr/src/uts which relate to ppc
arch ? That would allow us to point to the most important things
right away.
Regards,
Cyril
