Re: [PATCH v1] MdePkg: SMMUv3 updates for IORT table definitions

["Gao, Liming" <liming.gao@intel.com>]

Sami:
  I open http://infocenter.arm.com/help/topic/com.arm.doc.den0049c/DEN0049C_IO_Remapping_Table.pdf, and find the latest version is March 2018 Revision D. Do you check the latest version?

Thanks
Liming
