- 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.
