The software SMI Command IO Port is currently used in SecurityPkg to support the Physical Presence Interface. The IO port is hardcoded as 0xB2 in Tpm.asl. This patch series adds a PCD to SecurityPkg with the default value of 0xB2. The PCD is also used as the IO port value in Tpm.asl. Some existing platforms use IO port 0xB0 so this allows those platforms to set the value to 0xB0 in their platform DSC. On a separate note, shallow threading might not work on this patch series due to changes made by the SMTP server. Please bear with me while I am investigating if this can be changed.
