Subject: freedreno: set SWAP bit based on format
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a64e2d9d9fc111c709d91bbad174b5a29b882245;p=mesa.git

freedreno: set SWAP bit based on format

Really this should be set based on buffer format, not on color vs
depth/stencil.  Probably there should be more formats that set the bit
as we add support for more render target formats.
