This provides the 'crosec' command which has 50 a number of sub-commands for performing EC tasks such as 51 updating its flash, accessing a small saved context area 52 and talking to the I2C bus behind the EC (if there is one). 53 54config CROS_EC 55 bool "Enable Chrome OS EC" 56 help 57 Enable access to the Chrome OS EC. This is a separate 58 microcontroller typically available on a SPI bus on Chromebooks. It 59 provides access to the keyboard, some internal storage and may 60 control access to the battery and main PMIC depending on the 61 device. You can use the 'crosec' command to access it. 62 63config CROS_EC_I2C 64 bool "Enable Chrome OS EC I2C driver" 65 depends on CROS_EC 66 help 67 Enable I2C access to the Chrome OS EC. This is used on older 68 ARM Chromebooks such as snow and spring before the standard bus 69 changed to SPI.

This supports 86 keyboard (use the -l flag to enable the LCD), verified boot context, 87 EC flash read/write/erase support and a few other things. It is 88 enough to perform a Chrome OS verified boot on sandbox. 89 90config CROS_EC_SPI 91 bool "Enable Chrome OS EC SPI driver" 92 depends on CROS_EC 93 help 94 Enable SPI access to the Chrome OS EC. This is used on newer 95 ARM Chromebooks such as pit, pi and nyan-big.
