[Qemu-devel] [PATCH 19/20] smbios: Add a function to directly add an entry

[minyard@acm.org]

From: Corey Minyard <cminyard@mvista.com>

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.
