+config CMD_CROS_EC
+       bool "Enable crosec command"
+       depends on CROS_EC
+       help
+         Enable command-line access to the Chrome OS EC (Embedded
+         Controller). This provides the 'crosec' command which has
+         a number of sub-commands for performing EC tasks such as
+         updating its flash, accessing a small saved context area
+         and talking to the I2C bus behind the EC (if there is one).
+
+config CROS_EC
+       bool "Enable Chrome OS EC"
+       help
+         Enable access to the Chrome OS EC. This is a separate
+         microcontroller typically available on a SPI bus on Chromebooks. It
+         provides access to the keyboard, some internal storage and may
+         control access to the battery and main PMIC depending on the
+         device. You can use the 'crosec' command to access it.
+
+config CROS_EC_I2C
+       bool "Enable Chrome OS EC I2C driver"
+       depends on CROS_EC
+       help
+         Enable I2C access to the Chrome OS EC. This is used on older
+         ARM Chromebooks such as snow and spring before the standard bus
+         changed to SPI. The EC will accept commands across the I2C using
+         a special message protocol, and provide responses.
+
+config CROS_EC_LPC
+       bool "Enable Chrome OS EC LPC driver"
+       depends on CROS_EC
+       help
+         Enable I2C access to the Chrome OS EC. This is used on x86
+         Chromebooks such as link and falco. The keyboard is provided
+         through a legacy port interface, so on x86 machines the main
+         function of the EC is power and thermal management.
+
+config CROS_EC_SPI
+       bool "Enable Chrome OS EC SPI driver"
+       depends on CROS_EC
+       help
+         Enable SPI access to the Chrome OS EC. This is used on newer
+         ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
+         provides a faster and more robust interface than I2C but the bugs
+         are less interesting.
+
+config DM_CROS_EC
+       bool "Enable Driver Model for Chrome OS EC"
+       depends on DM
+       help
+         Enable driver model for the Chrome OS EC interface. This
+         allows the cros_ec SPI driver to operate with CONFIG_DM_SPI
+         but otherwise makes few changes. Since cros_ec also supports
+         LPC (which doesn't support driver model yet), a full
+         conversion is not yet possible.
+
+config FSL_SEC_MON
+       bool "Enable FSL SEC_MON Driver"
+       help
+         Freescale Security Monitor block is responsible for monitoring
+         system states.
+         Security Monitor can be transitioned on any security failures,
+         like software violations or hardware security violations.
