menuconfig BOOTCOUNT_LIMIT

help
Enable checking for exceeding the boot count limit.

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
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_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.

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_AT91
bool "Boot counter for Atmel AT91SAM9XE"
depends on AT91SAM9XE
config DM_BOOTCOUNT
bool "Boot counter in a device-model device"
help
Enables reading/writing the bootcount in a device-model based
backing store. If an entry in /chosen/u-boot,bootcount-device
exists, this will be the preferred bootcount device; otherwise
the first available bootcount device will be used.
endchoice

help
Enabled reading/writing the bootcount in a DM RTC device.
The wrapper device is to be specified with the compatible string
'u-boot,bootcount-rtc' and the 'rtc'-property (a phandle pointing
to the underlying RTC device) and an optional 'offset' property
are supported.
Accesses to the backing store are performed using the write16
and read16 ops of DM RTC devices.

bool "Support i2c eeprom devices as a backing store for bootcount"
depends on I2C_EEPROM
help
Enabled reading/writing the bootcount in a DM i2c eeprom device.
The wrapper device is to be specified with the compatible string
'u-boot,bootcount-i2c-eeprom' and the 'i2c-eeprom'-property (a phandle
pointing to the underlying i2c eeprom device) and an optional 'offset'
property are supported.

is not cleared on softreset.

Set the Maximum number of reboot cycles allowed without the boot
counter being cleared.
If set to 0 do not set a boot limit in the environment.

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

help
This option enables packing boot count magic value and boot count
into single word (32 bits).

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

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