This provides the 'crosec' command which has 296fb9ac15SSimon Glass a number of sub-commands for performing EC tasks such as 306fb9ac15SSimon Glass updating its flash, accessing a small saved context area 316fb9ac15SSimon Glass and talking to the I2C bus behind the EC (if there is one). 326fb9ac15SSimon Glass 336fb9ac15SSimon Glassconfig CROS_EC 346fb9ac15SSimon Glass bool "Enable Chrome OS EC" 356fb9ac15SSimon Glass help 366fb9ac15SSimon Glass Enable access to the Chrome OS EC. This is a separate 376fb9ac15SSimon Glass microcontroller typically available on a SPI bus on Chromebooks. It 386fb9ac15SSimon Glass provides access to the keyboard, some internal storage and may 396fb9ac15SSimon Glass control access to the battery and main PMIC depending on the 406fb9ac15SSimon Glass device. You can use the 'crosec' command to access it. 416fb9ac15SSimon Glass 426fb9ac15SSimon Glassconfig CROS_EC_I2C 436fb9ac15SSimon Glass bool "Enable Chrome OS EC I2C driver" 446fb9ac15SSimon Glass depends on CROS_EC 456fb9ac15SSimon Glass help 466fb9ac15SSimon Glass Enable I2C access to the Chrome OS EC. This is used on older 476fb9ac15SSimon Glass ARM Chromebooks such as snow and spring before the standard bus 486fb9ac15SSimon Glass changed to SPI. The EC will accept commands across the I2C using 496fb9ac15SSimon Glass a special message protocol, and provide responses. 506fb9ac15SSimon Glass 516fb9ac15SSimon Glassconfig CROS_EC_LPC 526fb9ac15SSimon Glass bool "Enable Chrome OS EC LPC driver" 536fb9ac15SSimon Glass depends on CROS_EC 546fb9ac15SSimon Glass help 556fb9ac15SSimon Glass Enable I2C access to the Chrome OS EC. This is used on x86 566fb9ac15SSimon Glass Chromebooks such as link and falco. The keyboard is provided 576fb9ac15SSimon Glass through a legacy port interface, so on x86 machines the main 586fb9ac15SSimon Glass function of the EC is power and thermal management. 596fb9ac15SSimon Glass 6047cb8c65SSimon Glassconfig CROS_EC_SANDBOX 6147cb8c65SSimon Glass bool "Enable Chrome OS EC sandbox driver" 6247cb8c65SSimon Glass depends on CROS_EC && SANDBOX 6347cb8c65SSimon Glass help 6447cb8c65SSimon Glass Enable a sandbox emulation of the Chrome OS EC. This supports 6547cb8c65SSimon Glass keyboard (use the -l flag to enable the LCD), verified boot context, 6647cb8c65SSimon Glass EC flash read/write/erase support and a few other things. It is 6747cb8c65SSimon Glass enough to perform a Chrome OS verified boot on sandbox. 6847cb8c65SSimon Glass 696fb9ac15SSimon Glassconfig CROS_EC_SPI 706fb9ac15SSimon Glass bool "Enable Chrome OS EC SPI driver" 716fb9ac15SSimon Glass depends on CROS_EC 726fb9ac15SSimon Glass help 736fb9ac15SSimon Glass Enable SPI access to the Chrome OS EC. This is used on newer 746fb9ac15SSimon Glass ARM Chromebooks such as pit, pi and nyan-big. The SPI interface 756fb9ac15SSimon Glass provides a faster and more robust interface than I2C but the bugs 766fb9ac15SSimon Glass are less interesting. 776fb9ac15SSimon Glass 78c12e0d93SPeng Fanconfig FSL_SEC_MON 79fe78378dSgaurav rana bool "Enable FSL SEC_MON Driver" 80fe78378dSgaurav rana help 81fe78378dSgaurav rana Freescale Security Monitor block is responsible for monitoring 82fe78378dSgaurav rana system states. 83fe78378dSgaurav rana Security Monitor can be transitioned on any security failures, 84fe78378dSgaurav rana like software violations or hardware security violations. 851cdd9412SStefan Roese 861cdd9412SStefan Roeseconfig PCA9551_LED 871cdd9412SStefan Roese bool "Enable PCA9551 LED driver" 881cdd9412SStefan Roese help 891cdd9412SStefan Roese Enable driver for PCA9551 LED controller.
