SYS_BOOTCOUNT_ADDR: Set to the address where the bootcount and bootcount magic will be stored. config BOOTCOUNT_EXT bool "Boot counter on EXT filesystem" depends on FS_EXT4 select EXT4_WRITE help Add support for maintaining boot count in a file on an EXT filesystem. config BOOTCOUNT_AM33XX bool "Boot counter in AM33XX RTC IP block" depends on AM33XX || SOC_DA8XX select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX help A bootcount driver for the RTC IP block found on many TI platforms. This requires the RTC clocks, etc, to be enabled prior to use and not all boards with this IP block on it will have the RTC in use. config BOOTCOUNT_AM33XX_NVMEM bool "Boot counter in AM33XX RTC IP block with upgrade_available flag" depends on AM33XX select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX help Add support for maintaining bootcount,upgrade_available, version and BOOTMAGIC in a AM33xx RTC IP block scratch register2. A bootcount driver for the RTC IP block found on many TI platforms. This requires the RTC clocks, etc, to be enabled prior to use and not all boards with this IP block on it will have the RTC in use. If there is upgrade in software then "upgrade_available" is 1, "bootcount" is incremented otherwise "upgrade_available" and "bootcount" is always 0. So the Userspace Application must set the "upgrade_available" and "bootcount" variable to 0, if a boot was successfully. config BOOTCOUNT_ENV bool "Boot counter in environment" help If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is used. If "upgrade_available" is 0, "bootcount" is always 0. If "upgrade_available" is 1, "bootcount" is incremented in the environment. So the Userspace Application must set the "upgrade_available" and "bootcount" variables to 0, if the system booted successfully. config BOOTCOUNT_RAM bool "Boot counter in RAM" help Store the bootcount in DRAM protected against bit errors due to short power loss or holding a system in RESET. config BOOTCOUNT_I2C bool "Boot counter on I2C device" help Enable support for the bootcounter on an i2c (like RTC) device.

This works only, if the PMIC is not connected to a battery. config DM_BOOTCOUNT_SPI_FLASH bool "Support SPI flash devices as a backing store for bootcount" depends on DM_SPI_FLASH help Enabled reading/writing the bootcount in a DM SPI flash device. The wrapper device is to be specified with the compatible string 'u-boot,bootcount-spi-flash' and the 'spi-flash'-property (a phandle pointing to the underlying SPI flash device) and an optional 'offset' property are supported. config BOOTCOUNT_MEM bool "Support memory based bootcounter" help Enabling Memory based bootcount, typically in a SoC register which is not cleared on softreset. compatible = "u-boot,bootcount"; config DM_BOOTCOUNT_SYSCON bool "Support SYSCON devices as a backing store for bootcount" select REGMAP select SYSCON help Enable reading/writing the bootcount value in a DM SYSCON device. The driver supports a fixed 32 bits size register using the native endianness. However, this can be controlled from the SYSCON DT node configuration. Accessing the backend is done using the regmap interface. endmenu endif config BOOTCOUNT_BOOTLIMIT int "Maximum number of reboot cycles allowed" default 0 help Set the Maximum number of reboot cycles allowed without the boot counter being cleared.
