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

14 prompt "Boot count device"
15 default BOOTCOUNT_AM33XX if AM33XX || SOC_DA8XX
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"
33 Add support for maintaining boot count in a file on an EXT
36 config BOOTCOUNT_AM33XX
37 bool "Boot counter in AM33XX RTC IP block"
38 depends on AM33XX || SOC_DA8XX
39 select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX
41 A bootcount driver for the RTC IP block found on many TI platforms.
42 This requires the RTC clocks, etc, to be enabled prior to use and
43 not all boards with this IP block on it will have the RTC in use.
46 bool "Boot counter in environment"
48 If no softreset save registers are found on the hardware
49 "bootcount" is stored in the environment. To prevent a
50 saveenv on all reboots, the environment variable
51 "upgrade_available" is used. If "upgrade_available" is
52 0, "bootcount" is always 0, if "upgrade_available" is
53 1 "bootcount" is incremented in the environment.
54 So the Userspace Application must set the "upgrade_available"
55 and "bootcount" variable to 0, if a boot was successfully.
58 bool "Boot counter in RAM"
60 Store the bootcount in DRAM protected against against bit errors
61 due to short power loss or holding a system in RESET.
64 bool "Boot counter on I2C device"
66 Enable support for the bootcounter on an i2c (like RTC) device.
67 CONFIG_SYS_I2C_RTC_ADDR = i2c chip address
68 CONFIG_SYS_BOOTCOUNT_ADDR = i2c addr which is used for
72 bool "Boot counter for Atmel AT91SAM9XE"
76 bool "Boot counter in a device-model device"
78 Enables reading/writing the bootcount in a device-model based
79 backing store. If an entry in /chosen/u-boot,bootcount-device
80 exists, this will be the preferred bootcount device; otherwise
81 the first available bootcount device will be used.
87 menu "Backing stores for device-model backed bootcount"
88 config DM_BOOTCOUNT_RTC
89 bool "Support RTC devices as a backing store for bootcount"
92 Enabled reading/writing the bootcount in a DM RTC device.
93 The wrapper device is to be specified with the compatible string
94 'u-boot,bootcount-rtc' and the 'rtc'-property (a phandle pointing
95 to the underlying RTC device) and an optional 'offset' property
98 Accesses to the backing store are performed using the write16
99 and read16 ops of DM RTC devices.
101 config DM_BOOTCOUNT_I2C_EEPROM
102 bool "Support i2c eeprom devices as a backing store for bootcount"
103 depends on I2C_EEPROM
105 Enabled reading/writing the bootcount in a DM i2c eeprom device.
106 The wrapper device is to be specified with the compatible string
107 'u-boot,bootcount-i2c-eeprom' and the 'i2c-eeprom'-property (a phandle
108 pointing to the underlying i2c eeprom device) and an optional 'offset'
109 property are supported.
112 bool "Support memory based bootcounter"
114 Enabling Memory based bootcount, typically in a SoC register which
115 is not cleared on softreset.
116 compatible = "u-boot,bootcount";
122 config BOOTCOUNT_BOOTLIMIT
123 int "Maximum number of reboot cycles allowed"
126 Set the Maximum number of reboot cycles allowed without the boot
127 counter being cleared.
128 If set to 0 do not set a boot limit in the environment.
130 config BOOTCOUNT_ALEN
131 int "I2C address length"
133 depends on BOOTCOUNT_I2C
135 Length of the the I2C address at SYS_BOOTCOUNT_ADDR for storing
138 config SYS_BOOTCOUNT_SINGLEWORD
139 bool "Use single word to pack boot count and magic value"
140 depends on BOOTCOUNT_GENERIC
142 This option enables packing boot count magic value and boot count
143 into single word (32 bits).
145 config SYS_BOOTCOUNT_EXT_INTERFACE
146 string "Interface on which to find boot counter EXT filesystem"
148 depends on BOOTCOUNT_EXT
150 Set the interface to use when locating the filesystem to use for the

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

172 depends on BOOTCOUNT_AM33XX || BOOTCOUNT_GENERIC || BOOTCOUNT_EXT || \
175 Set the address used for reading and writing the boot counter.
177 config SYS_BOOTCOUNT_MAGIC
178 hex "Magic value for the boot counter"
181 Set the magic value used for the boot counter.
