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".
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.
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.
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.
This option enables the kernel to search for a framebuffer in the coreboot table. If found, it is registered with simplefb.
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.
This option enables the kernel to expose the content of Google VPD under /sys/firmware/vpd.
