+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_SANDBOX
+       bool "Enable Chrome OS EC sandbox driver"
+       depends on CROS_EC && SANDBOX
+       help
+         Enable a sandbox emulation of the Chrome OS EC. This supports
+         keyboard (use the -l flag to enable the LCD), verified boot context,
+         EC flash read/write/erase support and a few other things. It is
+         enough to perform a Chrome OS verified boot on sandbox.
+
+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 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.
+
+config PCA9551_LED
+       bool "Enable PCA9551 LED driver"
+       help
+         Enable driver for PCA9551 LED controller. This controller
+         is connected via I2C. So I2C needs to be enabled.
+
+config PCA9551_I2C_ADDR
+       hex "I2C address of PCA9551 LED controller"
+       depends on PCA9551_LED
+       default 0x60
+       help
+         The I2C address of the PCA9551 LED controller.
+
+config RESET
+       bool "Enable support for reset drivers"
+       depends on DM
+       help
+         Enable reset drivers which can be used to reset the CPU or board.
+         Each driver can provide a reset method which will be called to
+         effect a reset. The uclass will try all available drivers when
+         reset_walk() is called.
