# SPDX-License-Identifier: GPL-2.0-onlymenuconfig GOOGLE_FIRMWARE	bool "Google Firmware Drivers"	default n	help	  These firmware drivers are used by Google servers,	  Chromebooks and other devices using coreboot firmware.	  If in doubt, say "N". if GOOGLE_FIRMWARE config GOOGLE_SMI	tristate "SMI interface for Google platforms"	depends on X86 && ACPI && DMI	help	  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. config GOOGLE_CBMEM	tristate "CBMEM entries in sysfs"	depends on GOOGLE_COREBOOT_TABLE	help	  CBMEM is a downwards-growing memory region created by the	  Coreboot BIOS containing tagged data structures from the	  BIOS.  These data structures expose things like the verified	  boot firmware variables, flash layout, firmware event log,	  and more. 	  This option enables the cbmem module, which causes the	  kernel to search for Coreboot CBMEM entries, and expose the	  memory for each entry in sysfs under	  /sys/bus/coreboot/devices/cbmem-<id>. config GOOGLE_COREBOOT_TABLE	tristate "Coreboot Table Access"	depends on HAS_IOMEM && (ACPI || OF)	help	  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. config GOOGLE_MEMCONSOLE	tristate	depends on GOOGLE_MEMCONSOLE_X86_LEGACY || GOOGLE_MEMCONSOLE_COREBOOT config GOOGLE_MEMCONSOLE_X86_LEGACY	tristate "Firmware Memory Console - X86 Legacy support"	depends on X86 && ACPI && DMI	select GOOGLE_MEMCONSOLE	help	  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. config GOOGLE_FRAMEBUFFER_COREBOOT	tristate "Coreboot Framebuffer"	depends on GOOGLE_COREBOOT_TABLE	help	  This option enables the kernel to search for a framebuffer in	  the coreboot table.  If found, it is registered with a platform	  device of type coreboot-framebuffer. Using the old device of	  type simple-framebuffer is deprecated. config GOOGLE_MEMCONSOLE_COREBOOT	tristate "Firmware Memory Console"	depends on GOOGLE_COREBOOT_TABLE	select GOOGLE_MEMCONSOLE	help	  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. config GOOGLE_VPD	tristate "Vital Product Data"	depends on GOOGLE_COREBOOT_TABLE	help	  This option enables the kernel to expose the content of Google VPD	  under /sys/firmware/vpd. endif # GOOGLE_FIRMWARE
