Subject: r200: Fix texture format regression on big endian systems.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dc88a96631c21c2bc2cdffefc8947e8924d77c91;p=mesa.git

r200: Fix texture format regression on big endian systems.

See https://bugs.freedesktop.org/show_bug.cgi?id=13324 .

Also use tx_table_be for VALID_FORMAT, in case r200SetTexImages ever gets
called for MESA_FORMAT_RGB888.
