[Qemu-devel] [PATCH 3/3] vga-pci: add qext region to mmio

2014-09-23 Thread Gerd Hoffmann
Add a qemu extented register range to the standard vga mmio bar. Right nowe there are two registers: One readonly register returning the size of the region (so we can easily add more registers there if needed) and one endian control register, so guests (especially ppc) can flip the framebuffer end
