freedreno: gallium driver for adreno
Currently works on a220. Others in the a2xx family look pretty similar and should be pretty straightforward to support with the same driver. The a3xx has a new shader ISA, and while many registers appear similar, the register addresses have been completely shuffled around. I am not sure yet whether it is best to support with the same driver, but different compiler, or whether it should be split into a different driver. v1: original v2: build file updates from review comments, and remove GPL licensed header files from msm kernel v3: smarter temp/pred register assignment, fix clear and depth/stencil format issues, resource_transfer fixes, scissor fixes Signed-off-by: Rob Clark <robdclark@gmail.com>
