SMM Revision Identifier
The SMM revision identifier at offset FEFCh in the SMM
state-save area specifies the version of SMM and the extensions
that are available on the processor. The SMM revision identifier
fields are as follows:
s Bits 31–18—Reserved
s Bit 17—SMM base address relocation (1 = enabled)
s Bit 16—I/O trap restart (1 = enabled)
s Bits 15–0—SMM revision level for the AMD-K6-2E processor
