This patch enables the correct detection of PIPE_FORMAT_R10G10B10A2_UINT
and PIPE_FORMAT_B10G10R10A2_UINT formats in r600g in big-endian mode.
Because the swapping doesn't happen on component boundaries for these
formats, the GPU H/W needs to be configured differently for LE/BE.
Therefore, we need to use a different color format for BE -
V_0280A0_COLOR_10_10_10_2
This enables support for ARB_texture_rgb10_a2ui, which otherwise is not
detected as supported.
Tested using piglit texwrap with GL_ARB_texture_rgb10_a2ui.
v2:
- Used the correct color format for R10G10B10A2 on
BE (V_0280A0_COLOR_10_10_10_2) to configure the GPU
- Added detection of this color format in endian swap function
- removed blank line
