this really looks like some structure internal to FSP that has fabricated into a HOB. […]
actually as Nate pointed out (offline) we already have standard ed2k hobs that communicate this information: HOB_TYPE_RESOURCE_DESCRIPTOR. I compiled with CONFIG_DISPLAY_HOBS and see tons of these. This is also how MinPlatform gets that information. So this may be used instead and we won't even need this HOB in the first place. Can we use that instead?
