[Qemu-devel] [PATCH 15/16] smbios: Add a function to directly add an ent


From: Corey Minyard
Subject: [Qemu-devel] [PATCH 15/16] smbios: Add a function to directly add an entry
Date: Tue, 12 Nov 2013 10:33:14 -0600

There was no way to directly add a table entry to the SMBIOS table,
even though the BIOS supports this.  So add a function to do this.
This is in preparation for the IPMI handler adding it's SMBIOS table
entry.
