10 help
11 Enable driver model for miscellaneous devices. This class is
12 used only for those do not fit other more general classes. A
13 set of generic read, write and ioctl methods may be used to
14 access the device.

17 bool "Enable crosec command"
18 depends on CROS_EC
19 help
20 Enable command-line access to the Chrome OS EC (Embedded
21 Controller). This provides the 'crosec' command which has
22 a number of sub-commands for performing EC tasks such as
23 updating its flash, accessing a small saved context area
24 and talking to the I2C bus behind the EC (if there is one).

26config CROS_EC
27 bool "Enable Chrome OS EC"
28 help
29 Enable access to the Chrome OS EC. This is a separate
30 microcontroller typically available on a SPI bus on Chromebooks. It
31 provides access to the keyboard, some internal storage and may
32 control access to the battery and main PMIC depending on the
33 device. You can use the 'crosec' command to access it.
34
35config CROS_EC_I2C
36 bool "Enable Chrome OS EC I2C driver"
37 depends on CROS_EC
38 help
39 Enable I2C access to the Chrome OS EC. This is used on older
40 ARM Chromebooks such as snow and spring before the standard bus
41 changed to SPI. The EC will accept commands across the I2C using
42 a special message protocol, and provide responses.
43
44config CROS_EC_LPC
45 bool "Enable Chrome OS EC LPC driver"
46 depends on CROS_EC
47 help
48 Enable I2C access to the Chrome OS EC. This is used on x86
49 Chromebooks such as link and falco. The keyboard is provided
50 through a legacy port interface, so on x86 machines the main
51 function of the EC is power and thermal management.

54 bool "Enable Chrome OS EC sandbox driver"
55 depends on CROS_EC && SANDBOX
56 help
57 Enable a sandbox emulation of the Chrome OS EC. This supports
58 keyboard (use the -l flag to enable the LCD), verified boot context,
59 EC flash read/write/erase support and a few other things. It is
60 enough to perform a Chrome OS verified boot on sandbox.

63 bool "Enable Chrome OS EC SPI driver"
64 depends on CROS_EC
65 help
66 Enable SPI access to the Chrome OS EC. This is used on newer
67 ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
68 provides a faster and more robust interface than I2C but the bugs
69 are less interesting.

74 Freescale Security Monitor block is responsible for monitoring
75 system states.
76 Security Monitor can be transitioned on any security failures,
77 like software violations or hardware security violations.

83 is connected via I2C. So I2C needs to be enabled.

93 bool "Enable support for reset drivers"
94 depends on DM
95 help
96 Enable reset drivers which can be used to reset the CPU or board.
97 Each driver can provide a reset method which will be called to
98 effect a reset. The uclass will try all available drivers when
99 reset_walk() is called.
