5 These firmware drivers are used by Google's servers. They are
6 only useful if you are working directly on one of their
7 proprietary servers. If in doubt, say "N".

14 help
15 Say Y here if you want to enable SMI callbacks for Google
16 platforms. This provides an interface for writing to and
17 clearing the event log. If EFI_VARS is also enabled this
18 driver provides an interface for reading and writing NVRAM
19 variables.

26 firmware modules access to the coreboot table. The coreboot table
27 pointer is accessed through the ACPI "GOOGCB00" object or the
