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"

21 details on the "Embedded Peripherals IP User Guide" of Altera.
24 bool "Support for Atmel ATSHA204A module"
27 Enable support for I2C connected Atmel's ATSHA204A
28 CryptoAuthentication module found for example on the Turris Omnia
32 bool "Rockchip e-fuse support"
35 Enable (read-only) access for the e-fuse block found in Rockchip
36 SoCs: accesses can either be made using byte addressing and a length
37 or through child-nodes that are generated based on the e-fuse map
38 retrieved from the DTS.
40 This driver currently supports the RK3399 only, but can easily be
41 extended (by porting the read function from the Linux kernel sources)
42 to support other recent Rockchip devices.
44 config VEXPRESS_CONFIG
45 bool "Enable support for Arm Versatile Express config bus"
48 If you say Y here, you will get support for accessing the
49 configuration bus on the Arm Versatile Express boards via
53 bool "Enable crosec command"
56 Enable command-line access to the Chrome OS EC (Embedded
57 Controller). This provides the 'crosec' command which has
58 a number of sub-commands for performing EC tasks such as
59 updating its flash, accessing a small saved context area
60 and talking to the I2C bus behind the EC (if there is one).
63 bool "Enable Chrome OS EC"
65 Enable access to the Chrome OS EC. This is a separate
66 microcontroller typically available on a SPI bus on Chromebooks. It
67 provides access to the keyboard, some internal storage and may
68 control access to the battery and main PMIC depending on the
69 device. You can use the 'crosec' command to access it.
72 bool "Enable Chrome OS EC I2C driver"
75 Enable I2C access to the Chrome OS EC. This is used on older
76 ARM Chromebooks such as snow and spring before the standard bus
77 changed to SPI. The EC will accept commands across the I2C using
78 a special message protocol, and provide responses.
81 bool "Enable Chrome OS EC LPC driver"
84 Enable I2C access to the Chrome OS EC. This is used on x86
85 Chromebooks such as link and falco. The keyboard is provided
86 through a legacy port interface, so on x86 machines the main
87 function of the EC is power and thermal management.
89 config CROS_EC_SANDBOX
90 bool "Enable Chrome OS EC sandbox driver"
91 depends on CROS_EC && SANDBOX
93 Enable a sandbox emulation of the Chrome OS EC. This supports
94 keyboard (use the -l flag to enable the LCD), verified boot context,
95 EC flash read/write/erase support and a few other things. It is
96 enough to perform a Chrome OS verified boot on sandbox.
99 bool "Enable Chrome OS EC SPI driver"
102 Enable SPI access to the Chrome OS EC. This is used on newer
103 ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
104 provides a faster and more robust interface than I2C but the bugs
105 are less interesting.
108 bool "Enable support for DS4510 CPU supervisor"
110 Enable support for the Maxim DS4510 CPU supervisor. It has an
111 integrated 64-byte EEPROM, four programmable non-volatile I/O pins
112 and a configurable timer for the supervisor function. The device is

120 Security Monitor can be transitioned on any security failures,
121 like software violations or hardware security violations.
124 bool "Enable MXC OCOTP Driver"
126 If you say Y here, you will get support for the One Time
127 Programmable memory pages that are stored on the some
128 Freescale i.MX processors.
130 config NUVOTON_NCT6102D
131 bool "Enable Nuvoton NCT6102D Super I/O driver"
133 If you say Y here, you will get support for the Nuvoton
134 NCT6102D Super I/O driver. This can be used to enable or
135 disable the legacy UART, the watchdog or other devices
136 in the Nuvoton Super IO chips on X86 platforms.
139 bool "Enable power-sequencing drivers"
142 Power-sequencing drivers provide support for controlling power for
143 devices. They are typically referenced by a phandle from another
144 device. When the device is started up, its power sequence can be
148 bool "Enable power-sequencing drivers for SPL"
151 Power-sequencing drivers provide support for controlling power for
152 devices. They are typically referenced by a phandle from another
153 device. When the device is started up, its power sequence can be
157 bool "Enable PCA9551 LED driver"
159 Enable driver for PCA9551 LED controller. This controller
160 is connected via I2C. So I2C needs to be enabled.
162 config PCA9551_I2C_ADDR
163 hex "I2C address of PCA9551 LED controller"
164 depends on PCA9551_LED
167 The I2C address of the PCA9551 LED controller.
170 bool "Enable STM32MP fuse wrapper providing the fuse API"
171 depends on ARCH_STM32MP && MISC
172 default y if CMD_FUSE
174 If you say Y here, you will get support for the fuse API (OTP)
175 for STM32MP architecture.
176 This API is needed for CMD_FUSE.
179 bool "Enable RCC driver for the STM32 SoC's family"
180 depends on (STM32 || ARCH_STM32MP) && MISC
182 Enable the STM32 RCC driver. The RCC block (Reset and Clock Control
183 block) is responsible of the management of the clock and reset
185 This driver is similar to an MFD driver in the Linux kernel.
188 bool "Enable support for the Tegra CAR driver"
189 depends on TEGRA_NO_BPMP
191 The Tegra CAR (Clock and Reset Controller) is a HW module that
192 controls almost all clocks and resets in a Tegra SoC.
195 bool "Enable support for the Tegra186 BPMP driver"
198 The Tegra BPMP (Boot and Power Management Processor) is a separate
199 auxiliary CPU embedded into Tegra to perform power management work,
200 and controls related features such as clocks, resets, power domains,
201 PMIC I2C bus, etc. This driver provides the core low-level
202 communication path by which feature-specific drivers (such as clock)
203 can make requests to the BPMP. This driver is similar to an MFD
204 driver in the Linux kernel.
207 bool "Enable TWL4030 LED controller"
209 Enable this to add support for the TWL4030 LED controller.
211 config WINBOND_W83627
212 bool "Enable Winbond Super I/O driver"
214 If you say Y here, you will get support for the Winbond
215 W83627 Super I/O driver. This can be used to enable the
216 legacy UART or other devices in the Winbond Super IO chips
222 Hidden option to enable QEMU fw_cfg interface. This will be selected by
223 either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.

277 hex "EEPROM Address Overflow"
280 EEPROM chips that implement "address overflow" are ones
281 like Catalyst 24WC04/08/16 which has 9/10/11 bits of
282 address and the extra bits end up in the "chip address" bit
283 slots. This makes a 24WC08 (1Kbyte) chip look like four 256
