PS1, Line 341: VR_DOMAIN_GT
> I followed the FSP code to get those domains. In FSP code they are talking about all these domains.

FSP has a comment that "Only VCCIN VR Exist" and the GetMaxNumVrs() function is hardcoded to return 1, so even though the FSP header has an array of 5 values it seems that only the first value will ever be used.
