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

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

26 This option enables the coreboot_table module, which provides other
27 firmware modules access to the coreboot table. The coreboot table
28 pointer is accessed through the ACPI "GOOGCB00" object or the
29 device tree node /firmware/coreboot.
30 If unsure say N.
