8 bool "Enable Driver Model for Misc drivers"
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
17 bool "Altera Sysid support"
20 Select this to enable a sysid for Altera devices. Please find
21 details on the "Embedded Peripherals IP User Guide" of Altera.
24 bool "Enable crosec command"
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).
34 bool "Enable Chrome OS EC"
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.
43 bool "Enable Chrome OS EC I2C driver"
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.
52 bool "Enable Chrome OS EC LPC driver"
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.
60 config CROS_EC_SANDBOX
61 bool "Enable Chrome OS EC sandbox driver"
62 depends on CROS_EC && SANDBOX
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.
70 bool "Enable Chrome OS EC SPI driver"
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
79 bool "Enable FSL SEC_MON Driver"
81 Freescale Security Monitor block is responsible for monitoring
83 Security Monitor can be transitioned on any security failures,
84 like software violations or hardware security violations.
87 bool "Enable MXC OCOTP Driver"
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.
94 bool "Enable power-sequencing drivers"
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
103 bool "Enable power-sequencing drivers for SPL"
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
112 bool "Enable PCA9551 LED driver"
114 Enable driver for PCA9551 LED controller. This controller
115 is connected via I2C. So I2C needs to be enabled.
117 config PCA9551_I2C_ADDR
118 hex "I2C address of PCA9551 LED controller"
119 depends on PCA9551_LED
122 The I2C address of the PCA9551 LED controller.
125 bool "Enable support for system reset drivers"
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.
133 config WINBOND_W83627
134 bool "Enable Winbond Super I/O driver"
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
144 Hidden option to enable QEMU fw_cfg interface. This will be selected by
145 either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
