Subject: only enable GL_MESA_ycbcr_texture for real r200 chips, not the derivatives, since... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fdb7ef8779adf6ae07c73bb0559651846fbe8c6;p=mesa.git

only enable GL_MESA_ycbcr_texture for real r200 chips, not the derivatives, since yuv textures do not work for some reason on the other chips.
