Subject: [PATCH 0/3] Add MCTP-over-KCS transport binding
Date: Thu, 28 Sep 2023 15:30:06 +0300	[thread overview]
Message-ID: <20230928123009.2913-1-aladyshev22@gmail.com> (raw)

This change adds a MCTP KCS transport binding, as defined by the DMTF
specificiation DSP0254 - "MCTP KCS Transport Binding".
A MCTP protocol network device is created for each KCS channel found in
the system.
The interrupt code for the KCS state machine is based on the current
IPMI KCS driver.
Since the KCS subsystem code is now used both in IPMI and MCTP drivers
the separate patchsets move KCS subsystem includes to a common folder.

Tested:
PLDM communication between the HOST and BMC was tested with both
components implemented via open-source software:
- The HOST (UEFI firmware) part was based one the edk2 [1] and
edk2-platforms [2] code,
- The BMC part was based on the openbmc [3] distribution.

The testing process and all the necessary utilities are described in
the [4] repository.
