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.

58 If there is upgrade in software then "upgrade_available" is 1,
59 "bootcount" is incremented otherwise "upgrade_available" and
60 "bootcount" is always 0. So the Userspace Application must set
61 the "upgrade_available" and "bootcount" variable to 0, if a boot
65 bool "Boot counter in environment"
67 If no softreset save registers are found on the hardware
68 "bootcount" is stored in the environment. To prevent a
69 saveenv on all reboots, the environment variable
70 "upgrade_available" is used. If "upgrade_available" is
71 0, "bootcount" is always 0, if "upgrade_available" is
72 1 "bootcount" is incremented in the environment.
73 So the Userspace Application must set the "upgrade_available"
74 and "bootcount" variable to 0, if a boot was successfully.
77 bool "Boot counter in RAM"
79 Store the bootcount in DRAM protected against against bit errors
80 due to short power loss or holding a system in RESET.
83 bool "Boot counter on I2C device"
85 Enable support for the bootcounter on an i2c (like RTC) device.

91 bool "Boot counter for Atmel AT91SAM9XE"
95 bool "Boot counter in a device-model device"
97 Enables reading/writing the bootcount in a device-model based
98 backing store. If an entry in /chosen/u-boot,bootcount-device
99 exists, this will be the preferred bootcount device; otherwise
100 the first available bootcount device will be used.

108 bool "Support RTC devices as a backing store for bootcount"
111 Enabled reading/writing the bootcount in a DM RTC device.
112 The wrapper device is to be specified with the compatible string
113 'u-boot,bootcount-rtc' and the 'rtc'-property (a phandle pointing
114 to the underlying RTC device) and an optional 'offset' property
117 Accesses to the backing store are performed using the write16

144 is not cleared on softreset.

147 config DM_BOOTCOUNT_SYSCON
148 bool "Support SYSCON devices as a backing store for bootcount"
152 Enable reading/writing the bootcount value in a DM SYSCON device.
153 The driver supports a fixed 32 bits size register using the native
154 endianness. However, this can be controlled from the SYSCON DT node
157 Accessing the backend is done using the regmap interface.
163 config BOOTCOUNT_BOOTLIMIT
164 int "Maximum number of reboot cycles allowed"
167 Set the Maximum number of reboot cycles allowed without the boot
168 counter being cleared.
