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"
74 bool "Boot counter in a device-model device"
76 Enables reading/writing the bootcount in a device-model based
77 backing store. If an entry in /chosen/u-boot,bootcount-device
78 exists, this will be the preferred bootcount device; otherwise
79 the first available bootcount device will be used.
85 menu "Backing stores for device-model backed bootcount"
86 config DM_BOOTCOUNT_RTC
87 bool "Support RTC devices as a backing store for bootcount"
90 Enabled reading/writing the bootcount in a DM RTC device.
91 The wrapper device is to be specified with the compatible string
92 'u-boot,bootcount-rtc' and the 'rtc'-property (a phandle pointing
93 to the underlying RTC device) and an optional 'offset' property
96 Accesses to the backing store are performed using the write16
97 and read16 ops of DM RTC devices.
99 config DM_BOOTCOUNT_I2C_EEPROM
100 bool "Support i2c eeprom devices as a backing store for bootcount"
101 depends on I2C_EEPROM
103 Enabled reading/writing the bootcount in a DM i2c eeprom device.
104 The wrapper device is to be specified with the compatible string
105 'u-boot,bootcount-i2c-eeprom' and the 'i2c-eeprom'-property (a phandle
106 pointing to the underlying i2c eeprom device) and an optional 'offset'
107 property are supported.
113 config BOOTCOUNT_BOOTLIMIT
114 int "Maximum number of reboot cycles allowed"
117 Set the Maximum number of reboot cycles allowed without the boot
118 counter being cleared.
119 If set to 0 do not set a boot limit in the environment.
121 config BOOTCOUNT_ALEN
122 int "I2C address length"
124 depends on BOOTCOUNT_I2C
126 Length of the the I2C address at SYS_BOOTCOUNT_ADDR for storing
129 config SYS_BOOTCOUNT_SINGLEWORD
130 bool "Use single word to pack boot count and magic value"
131 depends on BOOTCOUNT_GENERIC
133 This option enables packing boot count magic value and boot count
134 into single word (32 bits).

137 string "Interface on which to find boot counter EXT filesystem"
139 depends on BOOTCOUNT_EXT
141 Set the interface to use when locating the filesystem to use for the

153 string "Path and filename of the EXT filesystem based boot counter"

155 depends on BOOTCOUNT_EXT
157 Set the filename and path of the file used to store the boot counter.

166 Set the address used for reading and writing the boot counter.
168 config SYS_BOOTCOUNT_MAGIC
169 hex "Magic value for the boot counter"
172 Set the magic value used for the boot counter.
