[PATCH 4/5] drm/amdgpu: add psp microcode init for arcturus and aldebaran sriov vf

[Zhang, Hawking]

[AMD Official Use Only]

You can call psp_init_ta_microcode directly in sriov vf case so you don't need to initialize unnecessary psp firmware structures. 

Regards,
Hawking

Yeah, it will also init psp sos and asd mircrocode. But I think it's harmless.

Thanks,

This one  doesn't looks apply to  XGMI TA  only , it's for whole PSP init , can  you double check it ?
