Add PCIe scan option to BMC Feature Control command

This adds an option to enable and disable the PCIe scan feature using
the MTM BMC Feature Control command.

Changes to request bytes for PCIe scan feature:
Byte 1 – Supported features
    01h - PCIe scan
Byte 2 – Enable/Disable feature
    00h – Stops the given feature
    01h – Starts the given feature
    02h – Disables the given feature
    03h – Enables the given feature
Byte 3:5 – reserved

Tested:
Verified PCIe scan feature can be enabled/disabled as expected in MTM mode

Disable PCIe scan:
ipmitool raw 0x30 0xa4 1 2 0 0 0

Enable PCIe scan:
ipmitool raw 0x30 0xa4 1 3 0 0 0

Intel IPMI OEM support library

This component is intended to provide Intel-specific IPMI[3] command handlers for OpenBMC. These handlers are intended to integrate BMC with servers based on Intel architecture.

Overview

intel-ipmi-oem serves as an extension[1] to OpenBMC IPMI daemon[2]. It is compiled as a shared library and intended to both:

  • override existing implementation of standard IPMI commands to comply with Intel-specific solutions,
  • provide implementation for non-standard OEM extensions.

Capabilities

Related features provided by the library are grouped in separate source files. Main extensions to vanilla OpenBMC IPMI stack are the following:

  • Acquiring SMBIOS data over IPMI
  • Commands for better integration with Intel hardware
  • Firmware update extensions
  • Extended parsing of IPMI Platform Events[4]
