used only for those do not fit other more general classes. A
|

set of generic read, write and ioctl methods may be used to

access the device.

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.

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.

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.
