5 Enable command-line access to the Chrome OS EC (Embedded
6 Controller). This provides the 'crosec' command which has
7 a number of sub-commands for performing EC tasks such as
8 updating its flash, accessing a small saved context area
9 and talking to the I2C bus behind the EC (if there is one).

12 bool "Enable Chrome OS EC"
13 help
14 Enable access to the Chrome OS EC. This is a separate
15 microcontroller typically available on a SPI bus on Chromebooks. It
16 provides access to the keyboard, some internal storage and may
17 control access to the battery and main PMIC depending on the
18 device. You can use the 'crosec' command to access it.

22 depends on CROS_EC
23 help
24 Enable I2C access to the Chrome OS EC. This is used on older
25 ARM Chromebooks such as snow and spring before the standard bus
26 changed to SPI. The EC will accept commands across the I2C using
27 a special message protocol, and provide responses.

29config CROS_EC_LPC
30 bool "Enable Chrome OS EC LPC driver"
31 depends on CROS_EC
32 help
33 Enable I2C access to the Chrome OS EC. This is used on x86
34 Chromebooks such as link and falco. The keyboard is provided
35 through a legacy port interface, so on x86 machines the main
36 function of the EC is power and thermal management.

41 help
42 Enable a sandbox emulation of the Chrome OS EC. This supports
43 keyboard (use the -l flag to enable the LCD), verified boot context,
44 EC flash read/write/erase support and a few other things. It is
45 enough to perform a Chrome OS verified boot on sandbox.

49 depends on CROS_EC
50 help
51 Enable SPI access to the Chrome OS EC. This is used on newer
52 ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
53 provides a faster and more robust interface than I2C but the bugs
54 are less interesting.

79 depends on DM
80 help
81 Enable reset drivers which can be used to reset the CPU or board.
82 Each driver can provide a reset method which will be called to
83 effect a reset. The uclass will try all available drivers when
84 reset_walk() is called.
