[PATCH 0/5] Add support for access through an IPMB bus

[minyard]

This patch sets lets a devices that is sitting on an IPMB bus talk to
the BMC as a normal system interfaces.

It also adds the ability to message other MCs directly on the IPMB, and
it can receive commands and respond on the IPMB, too.

This is not meant as a replacement for ipmi_dev_int.c.  If you are doing
a full BMC, that's probably a better choice.  These changes are for
devices talking on the IPMB to BMCs or other MCs that might get some
commands to handle.
