From f0a704f9b506bdd7bd6396504c299058a26055ab Mon Sep 17 00:00:00 2001 From: Chao Li Date: Tue, 6 Sep 2022 15:53:36 +0800 Subject: [PATCH] MdePkg/Include: LoongArch definitions. REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4053 Add LoongArch processor related definitions. For the Http boot and PXE boot types seeing this URL section "Processor Architecture Type" for the LOONGARCH values: https://www.iana.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xhtml For definitions of PE/COFF and LOONGARCH relocation types, see the "Machine Types" and "Basic Relocation Types" sections of this URL for LOONGARCH values: https://docs.microsoft.com/en-us/windows/win32/debug/pe-format For the register definitions of exceptions context, see the UEFI V2.10 18.2.2, 18.2.4 and 18.2.5 sections of this URL for LOONGARCH definitions: https://uefi.org/specs/UEFI/2.10/18_Protocols_Debugger_Support.html Cc: Michael D Kinney Cc: Liming Gao Cc: Zhiguang Liu Signed-off-by: Chao Li Reviewed-by: Michael D Kinney Reviewed-by: Liming Gao --- MdePkg/Include/IndustryStandard/PeImage.h | 9 ++ MdePkg/Include/Protocol/DebugSupport.h | 107 ++++++++++++++++++++-- MdePkg/Include/Protocol/PxeBaseCode.h | 3 + MdePkg/Include/Uefi/UefiBaseType.h | 14 +++ MdePkg/Include/Uefi/UefiSpec.h | 16 ++-- 5 files changed, 136 insertions(+), 13 deletions(-) diff --git a/MdePkg/Include/IndustryStandard/PeImage.h b/MdePkg/Include/IndustryStandard/PeImage.h index 3109dc20f8..dd4cc25483 100644 --- a/MdePkg/Include/IndustryStandard/PeImage.h +++ b/MdePkg/Include/IndustryStandard/PeImage.h @@ -10,6 +10,7 @@ Copyright (c) 2006 - 2018, Intel Corporation.
