OvmfPkg: Add public headers from Xen Project. This patch imports publics headers in order to use features from Xen like XenStore, PV Block... There is only the necessary header files and there are only a few modifications in order to facilitate future merge of more recent header (that would be necessary to access new features). There is little modification compared to the original files: - Removed most of the unused part of the headers - Use of ZeroMem() instead of memset() - using #pragma pack(4) for IA32 compilation. - Replace types to be more UEFI compliant using a script. OVMF, when built for IA32 arch, uses the gcc switch -malign-double. This change the alignment of fields in some struct compare to what is espected by Xen and any backends. To fix the alignment, the #pragma pack(4) directive is used around the struct that need it. Command to run to change types: find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed --regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \; Avoid changing the 'long' that is not a type (with the first line). $ cat fix_type_in_xen_includes.sed /as long as/b s/([^a-zA-Z0-9_]|^)uint8_t([^a-zA-Z0-9_]|$)/\1UINT8\2/g s/([^a-zA-Z0-9_]|^)uint16_t([^a-zA-Z0-9_]|$)/\1UINT16\2/g s/([^a-zA-Z0-9_]|^)uint32_t([^a-zA-Z0-9_]|$)/\1UINT32\2/g s/([^a-zA-Z0-9_]|^)uint64_t([^a-zA-Z0-9_]|$)/\1UINT64\2/g s/([^a-zA-Z0-9_]|^)int8_t([^a-zA-Z0-9_]|$)/\1INT8\2/g s/([^a-zA-Z0-9_]|^)int16_t([^a-zA-Z0-9_]|$)/\1INT16\2/g s/([^a-zA-Z0-9_]|^)int32_t([^a-zA-Z0-9_]|$)/\1INT32\2/g s/([^a-zA-Z0-9_]|^)int64_t([^a-zA-Z0-9_]|$)/\1INT64\2/g s/([^a-zA-Z0-9_]|^)void([^a-zA-Z0-9_]|$)/\1VOID\2/g s/([^a-zA-Z0-9_]|^)unsigned int([^a-zA-Z0-9_]|$)/\1UINT32\2/g s/([^a-zA-Z0-9_]|^)int([^a-zA-Z0-9_]|$)/\1INT32\2/g s/([^a-zA-Z0-9_]|^)unsigned char([^a-zA-Z0-9_]|$)/\1UINT8\2/g s/([^a-zA-Z0-9_]|^)char([^a-zA-Z0-9_]|$)/\1CHAR8\2/g s/([^a-zA-Z0-9_]|^)unsigned long([^a-zA-Z0-9_]|$)/\1UINTN\2/g s/([^a-zA-Z0-9_]|^)long([^a-zA-Z0-9_]|$)/\1INTN\2/g Change in V4: - Add a README in Xen headers directory to explain what have been done to it.
