7config MISC
8	bool "Enable Driver Model for Misc drivers"
9	depends on DM
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.
15
16config ALTERA_SYSID
17	bool "Altera Sysid support"
18	depends on MISC
19	help
20	  Select this to enable a sysid for Altera devices. Please find
21	  details on the "Embedded Peripherals IP User Guide" of Altera.
22
23config CMD_CROS_EC
24	bool "Enable crosec command"
25	depends on CROS_EC
26	help
27	  Enable command-line access to the Chrome OS EC (Embedded
28	  Controller). This provides the 'crosec' command which has
29	  a number of sub-commands for performing EC tasks such as
30	  updating its flash, accessing a small saved context area
31	  and talking to the I2C bus behind the EC (if there is one).
32
33config CROS_EC
34	bool "Enable Chrome OS EC"
35	help
36	  Enable access to the Chrome OS EC. This is a separate
37	  microcontroller typically available on a SPI bus on Chromebooks. It
38	  provides access to the keyboard, some internal storage and may
39	  control access to the battery and main PMIC depending on the
40	  device. You can use the 'crosec' command to access it.
41
42config CROS_EC_I2C
43	bool "Enable Chrome OS EC I2C driver"
44	depends on CROS_EC
45	help
46	  Enable I2C access to the Chrome OS EC. This is used on older
47	  ARM Chromebooks such as snow and spring before the standard bus
48	  changed to SPI. The EC will accept commands across the I2C using
49	  a special message protocol, and provide responses.
50
51config CROS_EC_LPC
52	bool "Enable Chrome OS EC LPC driver"
53	depends on CROS_EC
54	help
55	  Enable I2C access to the Chrome OS EC. This is used on x86
56	  Chromebooks such as link and falco. The keyboard is provided
57	  through a legacy port interface, so on x86 machines the main
58	  function of the EC is power and thermal management.
59
60config CROS_EC_SANDBOX
61	bool "Enable Chrome OS EC sandbox driver"
62	depends on CROS_EC && SANDBOX
63	help
64	  Enable a sandbox emulation of the Chrome OS EC. This supports
65	  keyboard (use the -l flag to enable the LCD), verified boot context,
66	  EC flash read/write/erase support and a few other things. It is
67	  enough to perform a Chrome OS verified boot on sandbox.
68
69config CROS_EC_SPI
70	bool "Enable Chrome OS EC SPI driver"
71	depends on CROS_EC
72	help
73	  Enable SPI access to the Chrome OS EC. This is used on newer
74	  ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
75	  provides a faster and more robust interface than I2C but the bugs
76	  are less interesting.
77
78config FSL_SEC_MON
79	bool "Enable FSL SEC_MON Driver"
80	help
81	  Freescale Security Monitor block is responsible for monitoring
82	  system states.
83	  Security Monitor can be transitioned on any security failures,
84	  like software violations or hardware security violations.
85
86config MXC_OCOTP
87	bool "Enable MXC OCOTP Driver"
88	help
89	  If you say Y here, you will get support for the One Time
90	  Programmable memory pages that are stored on the some
91	  Freescale i.MX processors.
92
93config PWRSEQ
94	bool "Enable power-sequencing drivers"
95	depends on DM
96	help
97	  Power-sequencing drivers provide support for controlling power for
98	  devices. They are typically referenced by a phandle from another
99	  device. When the device is started up, its power sequence can be
100	  initiated.
101
102config SPL_PWRSEQ
103	bool "Enable power-sequencing drivers for SPL"
104	depends on PWRSEQ
105	help
106	  Power-sequencing drivers provide support for controlling power for
107	  devices. They are typically referenced by a phandle from another
108	  device. When the device is started up, its power sequence can be
109	  initiated.
110
111config PCA9551_LED
112	bool "Enable PCA9551 LED driver"
113	help
114	  Enable driver for PCA9551 LED controller. This controller
115	  is connected via I2C. So I2C needs to be enabled.
116
117config PCA9551_I2C_ADDR
118	hex "I2C address of PCA9551 LED controller"
119	depends on PCA9551_LED
120	default 0x60
121	help
122	  The I2C address of the PCA9551 LED controller.
123
124config SYSRESET
125	bool "Enable support for system reset drivers"
126	depends on DM
127	help
128	  Enable system reset drivers which can be used to reset the CPU or
129	  board. Each driver can provide a reset method which will be called
130	  to effect a reset. The uclass will try all available drivers when
131	  reset_walk() is called.
132
133config WINBOND_W83627
134	bool "Enable Winbond Super I/O driver"
135	help
136	  If you say Y here, you will get support for the Winbond
137	  W83627 Super I/O driver. This can be used to enable the
138	  legacy UART or other devices in the Winbond Super IO chips
139	  on X86 platforms.
140
141config QFW
142	bool
143	help
144	  Hidden option to enable QEMU fw_cfg interface. This will be selected by
145	  either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
