Subject: [PATCH V5 02/10] MdePkg: Increase EFI_RESOURCE_MAX_MEMORY_TYPE
Date: Tue,  1 Nov 2022 13:13:41 +0800	[thread overview]
Message-ID: <20221101051349.13-3-min.m.xu@intel.com> (raw)
In-Reply-To: <20221101051349.13-1-min.m.xu@intel.com>

From: Min M Xu <min.m.xu@intel.com>

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937

BZ3937_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 and update EFI_RESOURCE_MAX_MEMORY_TYPE
to 8. After BZ3937_EFI_RESOURCE_MEMORY_UNACCEPTED is officially published
in PI spec, we will re-visit here.
