1# 2# Multifunction miscellaneous devices 3# 4 5menu "Multifunction device drivers" 6 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 RESET 125 bool "Enable support for reset drivers" 126 depends on DM 127 help 128 Enable reset drivers which can be used to reset the CPU or board. 129 Each driver can provide a reset method which will be called to 130 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 141endmenu 142
