[Qemu-devel] [PATCH 10/17] ipmi: Add a firmware configuration repository

[minyard@acm.org]

From: Corey Minyard <cminyard@mvista.com>

Add a way for IPMI devices to register their firmware information
with the IPMI subsystem so that various firmware entities can pull
that information later for adding to firmware tables.
