# # Boot count configuration # menuconfig BOOTCOUNT_LIMIT bool "Enable support for checking boot count limit" help Enable checking for exceeding the boot count limit. More information: http://www.denx.de/wiki/DULG/UBootBootCountLimit if BOOTCOUNT_LIMIT choice prompt "Boot count device" default BOOTCOUNT_AM33XX if AM33XX || SOC_DA8XX default BOOTCOUNT_AT91 if AT91SAM9XE default BOOTCOUNT_GENERIC config BOOTCOUNT_GENERIC bool "Generic default boot counter" help Generic bootcount stored at SYS_BOOTCOUNT_ADDR. 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" 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 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_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" variable to 0, if a boot was successfully. config BOOTCOUNT_RAM bool "Boot counter in RAM" help Store the bootcount in DRAM protected against 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. CONFIG_SYS_I2C_RTC_ADDR = i2c chip address CONFIG_SYS_BOOTCOUNT_ADDR = i2c addr which is used for the bootcounter. CONFIG_BOOTCOUNT_ALEN = address len config BOOTCOUNT_AT91 bool "Boot counter for Atmel AT91SAM9XE" depends on AT91SAM9XE endchoice config SYS_BOOTCOUNT_SINGLEWORD bool "Use single word to pack boot count and magic value" depends on BOOTCOUNT_GENERIC help This option enables packing boot count magic value and boot count into single word (32 bits). config SYS_BOOTCOUNT_EXT_INTERFACE string "Interface on which to find boot counter EXT filesystem" default "mmc" depends on BOOTCOUNT_EXT help Set the interface to use when locating the filesystem to use for the boot counter. config SYS_BOOTCOUNT_EXT_DEVPART string "Partition of the boot counter EXT filesystem" default "0:1" depends on BOOTCOUNT_EXT help Set the partition to use when locating the filesystem to use for the boot counter. config SYS_BOOTCOUNT_EXT_NAME string "Path and filename of the EXT filesystem based boot counter" default "/boot/failures" depends on BOOTCOUNT_EXT help Set the filename and path of the file used to store the boot counter. config SYS_BOOTCOUNT_ADDR hex "RAM address used for reading and writing the boot counter" default 0x7000A000 depends on BOOTCOUNT_EXT help Set the address used for reading and writing the boot counter. endif
