^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) (Baseboard Management Controllers) and the KCS interface can be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) used to perform in-band IPMI communication with their host.
