BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902 The confidential computing guest type (GUEST_TYPE) was defined in OvmfPkg/Include/WorkArea.h. Now it is to be moved to MdePkg/Include/ConfidentialComputingGuestAttr.h and renamed as CC_GUEST_TYPE. There are 2 reasons for this change. 1. CC_GUEST_TYPE is a generic definition and will be used in CcProbeLib which is defined in MdePkg. 2. Based on the latest edk2 coding style: - First character should be upper case - Must contain lower case characters - No white space characters - Global variable name must start with a 'g' As the first step CC_GUEST_TYPE is defined in this patch. In the next patch GUEST_TYPE will be deleted. This is to make sure the bisect work correctly.
