menuconfig NVMEM bool "NVMEM Support" help Support for NVMEM(Non Volatile Memory) devices like EEPROM, EFUSES... This framework is designed to provide a generic interface to NVMEM If unsure, say no. if NVMEM config NVMEM_SNVS_LPGPR tristate "Freescale SNVS LPGPR support" select MFD_SYSCON help If you say yes here you get NVMEM support for the Freescale SNVS Low Power Generic Purpose Register (LPGPR). config IMX_OCOTP tristate "i.MX6 On Chip OTP controller" depends on ARCH_IMX6 || ARCH_VF610 || ARCH_IMX8MQ depends on OFDEVICE help This adds support for the i.MX6 On-Chip OTP controller. Currently the only supported functionality is reading the MAC address and assigning it to an ethernet device. config IMX_OCOTP_WRITE bool prompt "Enable write support of i.MX6 CPUs OTP fuses" depends on IMX_OCOTP help This adds write support to IMX6 On-Chip OTP registers. Example of set MAC to 12:34:56:78:9A:BC (2 words with address 0x22 (OCOTP_MAC0) and address 0x23 (OCOTP_MAC1)). To calculate the file offset multiply the value of the address by 4. mw -l -d /dev/imx-ocotp 0x8C 0x00001234 mw -l -d /dev/imx-ocotp 0x88 0x56789ABC config RAVE_SP_EEPROM tristate "Rave SP EEPROM Support" depends on RAVE_SP_CORE help Say y here to enable Rave SP EEPROM support. config EEPROM_93XX46 bool "Microwire EEPROM 93XX46 support" depends on SPI help Driver for the microwire EEPROM chipsets 93xx46x. The driver supports both read and write commands and also the command to erase the whole EEPROM. endif
