EFI_RESOURCE_MEMORY_UNACCEPTED is defined for unaccepted memory.
But this defitinion has not been officially in the PI spec. Base
on the code-first we define EFI_RESOURCE_MEMORY_UNACCEPTED at
MdeModulePkg/Include/Pi/PrePiHob.h.

in August.

I carefully checked the UEFI spec 2.10 but didn't find the unaccepted related changes in version 2.10. The latest one is in version 2.9. " 2134 Introduce unaccepted memory type "

Thanks

Hmm, seems PI spec has its own memory types instead if just using the
UEFI spec ones so unaccepted memory being in UEFI doesn't help here as
long as we don't have a new PI spec yet.  Is there any ETA for the next
PI spec update?

take care,
  Gerd
