[edk2-devel] [PATCH v2 1/4] DynamicTablesPkg: Define a SMBIOS Structure/Table type

Wed Mar 8 08:16:23 UTC 2023


SMBIOS Structure Types 0 through 127 (7Fh) are reserved
for and defined by the SMBIOS specification. Types 128
through 256 (80h to FFh) are available for system and
OEM-specific information.

Therefore, define a new type 'SMBIOS_TABLE_TYPE' that
represents a SMBIOS structure type and include it in
the definition of CM_STD_OBJ_SMBIOS_TABLE_INFO.
