This series introduces a generic VESA video driver and adjusts the generic PCI ROM support to support it. It also fixes up some problems which prevent this from working on PowerPC at present.
It is now possible to use VESA graphics: - On PowerPC, using the x86 emulator - On x86, using either the x86 emulator or native code execution
As it turns out, on the only platform I have tested (link), the x86 emulator is only slightly slower that native code execution (200ms difference). Still, we may as well leave this feature in there.
VGA ROMs are a very old technology but they are still used by modern platforms, including at least link and some Atom designs.
