Acked-by: Christian König <christian.koenig at amd.com> for this one 
because I can't verify the firmware numbers.

Reviewed-by: Christian König <christian.koenig at amd.com> for patch #2.

I can give the two patches a testing on bare metal Vega10 and Raven 
later today if nobody beats me on this.

Thanks for the patience, that looks *much* better now that we have an 
unified code path,
Christian.
