Can you point me to the code that does this? I don't see anything in pbus_size_mem() that treats ROMs differently. I'm considering reverting 5b28541552ef (assuming that would fix this radeon regression) because I think the radeon problem is worse than the 74151 problem and I think we can solve 74151 in a different way. Guo, Ben, this would affect you! It's too late to revert 5b28541552ef for v3.18, but we really need to work on this for v3.19. FOr 85491 (the radeon problem), we might be able to work around it by fixing the bridge window, but I'm not sure we could even get that done before v3.18. I'll work on that today.
