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

16 default BOOTCOUNT_AT91 if AT91SAM9XE
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
29 bool "Boot counter on EXT filesystem"
31 Add support for maintaining boot count in a file on an EXT
34 config BOOTCOUNT_AM33XX
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.
65 CONFIG_SYS_I2C_RTC_ADDR = i2c chip address
66 CONFIG_SYS_BOOTCOUNT_ADDR = i2c addr which is used for
70 bool "Boot counter for Atmel AT91SAM9XE"
75 config BOOTCOUNT_BOOTLIMIT
76 int "Maximum number of reboot cycles allowed"
79 Set the Maximum number of reboot cycles allowed without the boot
80 counter being cleared.
81 If set to 0 do not set a boot limit in the environment.
84 int "I2C address length"
86 depends on BOOTCOUNT_I2C
88 Length of the the I2C address at SYS_BOOTCOUNT_ADDR for storing
91 config SYS_BOOTCOUNT_SINGLEWORD
92 bool "Use single word to pack boot count and magic value"
93 depends on BOOTCOUNT_GENERIC
95 This option enables packing boot count magic value and boot count
96 into single word (32 bits).

131 hex "Magic value for the boot counter"
134 Set the magic value used for the boot counter.
