2019-04-10	drm/amdgpu: Introduce another ras enable function	xinhui pan	1	-0/+3
	Many parts of the whole SW stack can program the ras enablement state during the boot. Now we handle that case by adding one function which check the ras flags and choose different code path.

2019-03-19	drm/amdgpu: add new ras workflow control flags	xinhui pan	1	-0/+3
	add ras post init function. Do some initialization after all IP have finished their late init. Add new member flags which will control the ras work flow. For now, vbios enable ras for us on boot. That might change in the future. So there should be a flag from vbios to tell us if ras is enabled or not on boot. Looks like there is no such info now. Other bits of the flags are reserved to control other parts of ras.

2019-03-19	drm/amdgpu: add new member hw_supported	xinhui pan	1	-0/+3
	Currently, it is not clear how ras is supported. Both software and hardware can set the supported. That is confusing. Fix it by adding new member hw_supported.
