| 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 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 RESET | |
| bool "Enable support for reset drivers" | |
| depends on DM | |
| help | |
| Enable 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. | |
