[PATCH 0/1][SRU][B][OEM-B] AMD Prairie Falcon platform failed to boot up

[AceLan Kao]

BugLink: https://bugs.launchpad.net/bugs/1850572

[Impact]
AMD Prairie Falcon is the AME Embedded variant of Stoney. It fails to boot
up without disable its CGCG feature.
Set 'amdgpu.cg_mask=0xfffffffb' kernel parameter to disable CGCG

[Fix]
Suggestion from AMD that we have to cherry pick this commit which is
included in v4.16
   fb4bbba27753 drm/amdgpu: re-enable CGCG on CZ and disable on ST

[Test]
Verified on AMD Prairie Falcon platform, system boots up normally.

[Regression Potential]
Low, this commit has been included for more than one and a half year
in the upstream, should be pretty safe to include it.
