> This patch set defines a new VARIABLE_RUNTIME_CACHE_INFO HOB. The HOB is

variable

> In following patches, when PcdEnableVariableRuntimeCache is TRUE,
VariablePei
> will install a callback of gEfiPeiMemoryDiscoveredPpiGuid to allocate the
needed

> Then VariableSmmRuntimeDxe driver will consume
> gEdkiiVariableRuntimeCacheInfoHobGuid to initialize the variable runtime
cache
> related content. The code to allocate and unblock the runtime cache buffer
in
> VariableSmmRuntimeDxe is also removed in this patc set.
