Subject: [PATCH 2/4] gsmi: Add coreboot to list of matching BIOS vendors

From: Duncan Laurie <dlaurie@...omium.org>

In order to use this coreboot needs board support for:
CONFIG_ELOG=y
CONFIG_ELOG_GSMI=y

And the kernel driver needs enabled:
CONFIG_GOOGLE_GSMI=y

To test, verify that clean shutdown event is added to the log:

> mosys eventlog list | grep 'Clean Shutdown'
11 | 2012-06-25 09:49:24 | Kernl Event | Clean Shutdown
