   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".

  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.
