2019-04-10drm/amdgpu: Introduce another ras enable functionxinhui pan1-0/+27
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.

2019-03-19drm/amdgpu: add new ras workflow control flagsxinhui pan1-1/+33
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.
