Subject: drm/amdgpu: unify fw_write_wait for new gfx9 asics
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ba714a56fcb58782023514bb11455c549c572099;p=uclinux-h8%2Flinux.git

drm/amdgpu: unify fw_write_wait for new gfx9 asics

Make the fw_write_wait default case true since presumably all new
gfx9 asics will have updated firmware. That is using unique WAIT_REG_MEM
packet with opration=1.
