drm/radeon: upgrade to 1.27 - make PCI GART more flexible
radeon: make PCI GART aperture size variable, but making table size variable
This is precursor to getting a TTM backend for this stuff, and also
allows the PCI table to be allocated at fb 0
radeon: add support for reverse engineered xpress200m
The IGPGART setup code was traced using mmio-trace on fglrx by myself
and Phillip Ezolt <phillipezolt@gmail.com> on dri-devel.
This code doesn't let the 3D driver work properly as the card has no
vertex shader support.
Thanks to Matthew Garrett + Ubuntu for providing me some hardware to do this
work on.
