5 menuconfig BOOTCOUNT_LIMIT
6 bool "Enable support for checking boot count limit"
8 Enable checking for exceeding the boot count limit.

17 default BOOTCOUNT_GENERIC
19 config BOOTCOUNT_GENERIC
20 bool "Generic default boot counter"
22 Generic bootcount stored at SYS_BOOTCOUNT_ADDR.
25 Set to the address where the bootcount and bootcount magic

35 bool "Boot counter in AM33XX RTC IP block"
36 depends on AM33XX || SOC_DA8XX
37 select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX
39 A bootcount driver for the RTC IP block found on many TI platforms.
40 This requires the RTC clocks, etc, to be enabled prior to use and
41 not all boards with this IP block on it will have the RTC in use.
44 bool "Boot counter in environment"
46 If no softreset save registers are found on the hardware
47 "bootcount" is stored in the environment. To prevent a
48 saveenv on all reboots, the environment variable
49 "upgrade_available" is used. If "upgrade_available" is
50 0, "bootcount" is always 0, if "upgrade_available" is
51 1 "bootcount" is incremented in the environment.
52 So the Userspace Application must set the "upgrade_available"
53 and "bootcount" variable to 0, if a boot was successfully.
56 bool "Boot counter in RAM"
58 Store the bootcount in DRAM protected against against bit errors
59 due to short power loss or holding a system in RESET.
62 bool "Boot counter on I2C device"
64 Enable support for the bootcounter on an i2c (like RTC) device.

83 config SYS_BOOTCOUNT_SINGLEWORD
84 bool "Use single word to pack boot count and magic value"
85 depends on BOOTCOUNT_GENERIC
87 This option enables packing boot count magic value and boot count
88 into single word (32 bits).
