[Mesa-dev] [PATCH 003/140] amdgpu/addrlib: allow tileSplitBytes greater than row size

[Marek Olšák]

From: Xiao-Tao Zai <xaio-tao.zai at amd.com>

Carrizo row size is 1K, while tileSplitBytes is 2K for a 4xAA 32bpp
depth surface. Remove the sanity check that tileSplitBytes must be
greater than row size. There could be performance loss but may be
covered by non-split depth which enables tc-compatible read.
