+ The PchInitSmm module is a SMM driver that initializes the Intel Platform Controller Hub
+ SMM requirements and services. It consumes the PCH_POLICY_PROTOCOL for expected
+ configurations per policy.
+
+ - <b>Details</b>\n
+ This module provides SMI handlers to services PCIE HotPlug SMI, LinkActive SMI, and LinkEq SMI.
+ And also provides port 0x61 emulation support, GPIO Sx isolation requirement, and register BIOS WP
+ handler to process BIOSWP status.
