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

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.

help
Length of the the I2C address at SYS_BOOTCOUNT_ADDR for storing
the boot counter.
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

help
Set the interface to use when locating the filesystem to use for the
boot counter.

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.
