[PATCH 0/8] Handing IPMI for emulating BMC |

Baseboard Management Controllers (BMCs) are special
processors that monitors state of a computer, often
used in data center servers. They often communicate
via IPMI. As a result, it is important to emulate
the IPMI interface so that they can connect to host
machines.
This patch set aims to refactor the existing hw/ipmi
and make it handles both Core side and BMC side
emulations. We also added the implementation of the
KCS module for NPCM7XX BMC boards that work as a backend.
We have tested this patch on various NPCM7xx based
systems and they can communicate with a host that runs
`ipmi-bmc-extern`.
The structure is as follows:
Patch 1-3 contains some documentation written by
Havard Skinnomoen that how the emulation of existing
host-side IPMI and the new BMC-side IPMI works.
Patch 4-6 refactors the current IPMI code so that
they work for both host-side and BMC-side.
Patch 7 adds a new ipmi-host-extern which represents
BMC-side emulation that is similar to the current
ipmi-bmc-extern.
Patch 8 implements the KCS device in NPCM7XX boards. It
works as a backend to the ipmi-host-extern device. Since
the direction is different we can't directly use ipmi-kcs.c
for BMC emulation.
