Subject: [PATCH v2 5/6] UefiCpuPkg/MpInitLib: Relocate microcode patch fields in CPU_MP_DATA
Date: Wed, 25 Dec 2019 15:58:13 +0800	[thread overview]
Message-ID: <20191225075814.8372-6-hao.a.wu@intel.com> (raw)
In-Reply-To: <20191225075814.8372-1-hao.a.wu@intel.com>

The below 2 microcode patch related fields in structure CPU_MP_DATA:

  UINT64                         MicrocodePatchAddress;
  UINT64                         MicrocodePatchRegionSize;

They will be passed from PEI phase and be reused DXE phase.

Previously, these 2 fields were placed after some fields with type
'UINTN', this will lead to different field offset in different
architecture for them.

This commit will move them before the fields with different size in
different architecture to ensure they can be properly used in DXE phase.
