Overview

This module performs BMC initialization during the DXE phase as part of the AMI IPMI stack. It locates and initializes KCS transport to the BMC, runs a BMC self-test and publishes the BMC Self Test Protocol, checks the BMC firmware version (OEM-specific), and installs SMBIOS Type 42 (Management Controller Description) and SPMI ACPI table records. It also handles IPMI CMOS clear, boot flag settings, and BMC-related setup option configuration.
