GOOGLE_FIRMWARE

Google Firmware Drivers

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

GOOGLE_SMI

SMI interface for Google platforms

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

GOOGLE_COREBOOT_TABLE

Coreboot Table Access

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

GOOGLE_MEMCONSOLE_X86_LEGACY

Firmware Memory Console - X86 Legacy support

This option enables the kernel to search for a firmware log in
the EBDA on Google servers.  If found, this log is exported to
userland in the file /sys/firmware/log.

GOOGLE_FRAMEBUFFER_COREBOOT

Coreboot Framebuffer

This option enables the kernel to search for a framebuffer in
the coreboot table.  If found, it is registered with simplefb.

GOOGLE_MEMCONSOLE_COREBOOT

Firmware Memory Console

This option enables the kernel to search for a firmware log in
the coreboot table.  If found, this log is exported to userland
in the file /sys/firmware/log.

GOOGLE_VPD

Vital Product Data

This option enables the kernel to expose the content of Google VPD
under /sys/firmware/vpd.
