[PATCH 0/5] renouveau: nv30/nv40 unification
This patchset applies some minor fixes to renouveau.xml and then unifies
the nv30 and nv40 register definitions.
nv30 and nv40 are very similar and have the same offsets for the registers
they share.
The major differences are:
1. Texture setup is different due to full NPOT support on nv40
2. More advanced blending/render targets on nv40
3. NV30 has fixed function registers, which NV40 lacks
The
