[PATCH v2 0/2] drm/radeon: Sun XVR-300 support on sparc64

[Imre Kaloz <kaloz@kernel.org>]

These two patches get radeon KMS working on the Sun XVR-300, a
FireMV 2200 PCIe (RV370) board, in sparc64 hosts.

Patch 1 fixes an Oops that any posted radeon card on sparc64 hits in
igp_read_bios_from_vram(), which dereferences an ioremap() cookie to
check the VBIOS signature. It is tagged for stable.

Patch 2 adds a legacy connector table for the XVR-300, which has no
COMBIOS for the driver to parse, so both DVI-I outputs are found.
The XVR-300 needs both.

Tested on a Sun Ultra 45 with an XVR-300.

Changes in v2:
- Read the signature with readb() before the allocation instead of
  checking the RAM copy, as radeon_read_bios() does (patch 1).

Imre Kaloz (2):
  drm/radeon: Read the VRAM VBIOS signature with readb()
  drm/radeon: add a connector table for the Sun XVR-300
