From: Abner Chang <abner.ch...@amd.com>
Add edk2 driver that supports PLDM SMBIOS Transfer
Specification.
https://www.dmtf.org/sites/default/files/standards/documents/DSP0246_1.0.1.pdf
We currently only support "Push" mode of PLDM SMBIOS
transfer. That says only BIOS to BMC direction is
supported.
The functionality is verified by checking the binary
debug output of payload.
