That seems reasonable to me. I was reviewing the PI spec recently to get
Standalone MM information, it is pretty sparse in general, in particular
where it relates to HOBs. I think more clarification for Standalone MM
in relation to HOBs would be helpful.
I see you are already on the other thread
(StandaloneMMPkg: Fix HOB Space and heap space conflicted issue), where
we are discussing just such a confusion in the PI spec.
Thanks,
Oliver
