+menuconfig CHROME_PLATFORMS
+	bool "Platform support for Chrome hardware"
+	depends on X86 || ARM
+	---help---
+	  Say Y here to get to see options for platform support for
+	  various Chromebooks and Chromeboxes. This option alone does
+	  not add any kernel code.
+
+	  If you say N, all options in this submenu will be skipped and disabled.
+
+if CHROME_PLATFORMS
+
+config CHROMEOS_LAPTOP
+	tristate "Chrome OS Laptop"
+	depends on I2C && DMI && X86
+	---help---
+	  This driver instantiates i2c and smbus devices such as
+	  light sensors and touchpads.
+
+	  If you have a supported Chromebook, choose Y or M here.
+	  The module will be called chromeos_laptop.
+
+config CHROMEOS_PSTORE
+	tristate "Chrome OS pstore support"
+	depends on X86
+	---help---
+	  This module instantiates the persistent storage on x86 ChromeOS
+	  devices. It can be used to store away console logs and crash
+	  information across reboots.
+
+	  The range of memory used is 0xf00000-0x1000000, traditionally
+	  the memory used to back VGA controller memory.
+
+	  If you have a supported Chromebook, choose Y or M here.
+	  The module will be called chromeos_pstore.
+
+config CROS_EC_CHARDEV
+        tristate "Chrome OS Embedded Controller userspace device interface"
+        depends on MFD_CROS_EC
+        ---help---
+          This driver adds support to talk with the ChromeOS EC from userspace.
+
+          If you have a supported Chromebook, choose Y or M here.
+          The module will be called cros_ec_dev.
+
+config CROS_EC_LPC
+        tristate "ChromeOS Embedded Controller (LPC)"
+        depends on MFD_CROS_EC && (X86 || COMPILE_TEST)
+        help
+          If you say Y here, you get support for talking to the ChromeOS EC
+          over an LPC bus. This uses a simple byte-level protocol with a
+          checksum. This is used for userspace access only. The kernel
+          typically has its own communication methods.
+
+          To compile this driver as a module, choose M here: the
+          module will be called cros_ec_lpc.
