# # Multifunction miscellaneous devices # menu "Multifunction device drivers" config MISC bool "Enable Driver Model for Misc drivers" depends on DM help Enable driver model for miscellaneous devices. This class is used only for those do not fit other more general classes. A set of generic read, write and ioctl methods may be used to access the device. config ALTERA_SYSID bool "Altera Sysid support" depends on MISC help Select this to enable a sysid for Altera devices. Please find details on the "Embedded Peripherals IP User Guide" of Altera. config CMD_CROS_EC bool "Enable crosec command" depends on CROS_EC help Enable command-line access to the Chrome OS EC (Embedded Controller). This provides the 'crosec' command which has a number of sub-commands for performing EC tasks such as updating its flash, accessing a small saved context area and talking to the I2C bus behind the EC (if there is one). config CROS_EC bool "Enable Chrome OS EC" help Enable access to the Chrome OS EC. This is a separate microcontroller typically available on a SPI bus on Chromebooks. It provides access to the keyboard, some internal storage and may control access to the battery and main PMIC depending on the device. You can use the 'crosec' command to access it. config CROS_EC_I2C bool "Enable Chrome OS EC I2C driver" depends on CROS_EC help Enable I2C access to the Chrome OS EC. This is used on older ARM Chromebooks such as snow and spring before the standard bus changed to SPI. The EC will accept commands across the I2C using a special message protocol, and provide responses. config CROS_EC_LPC bool "Enable Chrome OS EC LPC driver" depends on CROS_EC help Enable I2C access to the Chrome OS EC. This is used on x86 Chromebooks such as link and falco. The keyboard is provided through a legacy port interface, so on x86 machines the main function of the EC is power and thermal management. config CROS_EC_SANDBOX bool "Enable Chrome OS EC sandbox driver" depends on CROS_EC && SANDBOX help Enable a sandbox emulation of the Chrome OS EC. This supports keyboard (use the -l flag to enable the LCD), verified boot context, EC flash read/write/erase support and a few other things. It is enough to perform a Chrome OS verified boot on sandbox. config CROS_EC_SPI bool "Enable Chrome OS EC SPI driver" depends on CROS_EC help Enable SPI access to the Chrome OS EC. This is used on newer ARM Chromebooks such as pit, pi and nyan-big. The SPI interface provides a faster and more robust interface than I2C but the bugs are less interesting. config FSL_SEC_MON bool "Enable FSL SEC_MON Driver" help Freescale Security Monitor block is responsible for monitoring system states. Security Monitor can be transitioned on any security failures, like software violations or hardware security violations. config MXC_OCOTP bool "Enable MXC OCOTP Driver" help If you say Y here, you will get support for the One Time Programmable memory pages that are stored on the some Freescale i.MX processors. config PWRSEQ bool "Enable power-sequencing drivers" depends on DM help Power-sequencing drivers provide support for controlling power for devices. They are typically referenced by a phandle from another device. When the device is started up, its power sequence can be initiated. config SPL_PWRSEQ bool "Enable power-sequencing drivers for SPL" depends on PWRSEQ help Power-sequencing drivers provide support for controlling power for devices. They are typically referenced by a phandle from another device. When the device is started up, its power sequence can be initiated. config PCA9551_LED bool "Enable PCA9551 LED driver" help Enable driver for PCA9551 LED controller. This controller is connected via I2C. So I2C needs to be enabled. config PCA9551_I2C_ADDR hex "I2C address of PCA9551 LED controller" depends on PCA9551_LED default 0x60 help The I2C address of the PCA9551 LED controller. config SYSRESET bool "Enable support for system reset drivers" depends on DM help Enable system reset drivers which can be used to reset the CPU or board. Each driver can provide a reset method which will be called to effect a reset. The uclass will try all available drivers when reset_walk() is called. config WINBOND_W83627 bool "Enable Winbond Super I/O driver" help If you say Y here, you will get support for the Winbond W83627 Super I/O driver. This can be used to enable the legacy UART or other devices in the Winbond Super IO chips on X86 platforms. config QFW bool help Hidden option to enable QEMU fw_cfg interface. This will be selected by either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE. endmenu
