# # Multifunction miscellaneous devices # menu "Multifunction device drivers" 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 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 MXC_OCOTP bool "Freescale OCOTP support" depends on ARCH_MX5 || ARCH_MX6 config MXS_OCOTP bool "Freescale OCOTP support" depends on ARCH_MXS 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. endmenu
