It seems no one cares for arch/ppc any more but the move to powerpc was not finished completely (PReP subarch was not migrated but sees users, I do not know about the user base of the other subarches). So I have been thinking about migrating PReP support to arch/powerpc myself since I use it.The merge is still on-going. So it's not "finished" at all.quoted
Any general guidelines or specific hints about that? I have looked around in the code and some pieces are clearly PReP specific (setup, pci, boot) but others seem wuite a bit mixed up with other subarches.David Gibson and Rob Landley had a quite interesting discussion about PReP last night on IRC. You might want to contact them and see if they came to any conclusions.
Yes, my draft PReP support patch, tweaked this morning to build again (changes roughly identical to Rob Landley's patch, I believe) is at: http://ozlabs.org/~dgibson/home/tmp/prep-support -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
