Tiled buffers have the same alignment requirements regardless of whether the surface is for db, cb, or textures. Previously, the calculations where inconsistent for each buffer type. - Unify the alignment calculations in a common function - Standardize the alignment units (pixels for pitch/height/depth, bytes for base) - properly check the buffer base alignments Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
