I'm trying to make some progress on this old series from Yinghai [1]. There's a lot more to do than just these first two patches, but maybe a tiny bit of incremental progress is better than none. The first patch ("Support arbitrary host bridge address offset") is unchanged from Yinghai's posting except for the changelog. I'm interested in feedback about the second ("Reserve System ROM and Video ROM") patch because it changes something that *looks* wrong to me, but I don't know anything about the Sparc address map. If this is on the right track, I'd like to merge these via my PCI tree in the hope that I can include more of Yinghai's patches as well.
