help
Generic bootcount stored at SYS_BOOTCOUNT_ADDR.
SYS_BOOTCOUNT_ADDR:
Set to the address where the bootcount and bootcount magic
will be stored.
config BOOTCOUNT_FS
bool "Boot counter on a filesystem"
help
Add support for maintaining boot count in a file on a filesystem.
This requires that you have enabled write support for the filesystem
that will be used by the partition that you configure this feature
for.

depends on AM33XX || SOC_DA8XX
select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX
help
A bootcount driver for the RTC IP block found on many TI platforms.
This requires the RTC clocks, etc, to be enabled prior to use and
not all boards with this IP block on it will have the RTC in use.
config BOOTCOUNT_AM33XX_NVMEM
bool "Boot counter in AM33XX RTC IP block with upgrade_available flag"
depends on AM33XX
select SPL_AM33XX_ENABLE_RTC32K_OSC if AM33XX
help
Add support for maintaining bootcount,upgrade_available,
version and BOOTMAGIC in a AM33xx RTC IP block
scratch register2.
A bootcount driver for the RTC IP block found on many TI platforms.
This requires the RTC clocks, etc, to be enabled prior to use and
not all boards with this IP block on it will have the RTC in use.
If there is upgrade in software then "upgrade_available" is 1,
"bootcount" is incremented otherwise "upgrade_available" and
"bootcount" is always 0. So the Userspace Application must set
the "upgrade_available" and "bootcount" variable to 0, if a boot
was successfully.
config BOOTCOUNT_ENV
bool "Boot counter in environment"
help
If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is used. If "upgrade_available" is
0, "bootcount" is always 0. If "upgrade_available" is 1,
"bootcount" is incremented in the environment.
So the Userspace Application must set the "upgrade_available"
and "bootcount" variables to 0, if the system booted successfully.
config BOOTCOUNT_RAM
bool "Boot counter in RAM"
help
Store the bootcount in DRAM protected against bit errors
due to short power loss or holding a system in RESET.
config BOOTCOUNT_AT91

depends on AT91SAM9XE
config DM_BOOTCOUNT
bool "Boot counter in a device-model device"
help
Enables reading/writing the bootcount in a device-model based
backing store. If an entry in /chosen/u-boot,bootcount-device
exists, this will be the preferred bootcount device; otherwise
the first available bootcount device will be used.

help
Enabled reading/writing the bootcount in a DM RTC device.
The wrapper device is to be specified with the compatible string
'u-boot,bootcount-rtc' and the 'rtc'-property (a phandle pointing
to the underlying RTC device) and an optional 'offset' property
are supported.
Accesses to the backing store are performed using the write16
and read16 ops of DM RTC devices.
config DM_BOOTCOUNT_I2C
bool "Driver Model boot counter on I2C device"
depends on DM_I2C
help
Enable support for the bootcounter on a generic i2c device, like a RTC
or PMIC. The bootcounter is configured in the device tree using the
"u-boot,bootcount-i2c" compatible string. It requires a phandle
'i2cbcdev' for the i2c device and an 'offset' property used within the
device.
config DM_BOOTCOUNT_I2C_EEPROM
bool "Support i2c eeprom devices as a backing store for bootcount"
depends on I2C_EEPROM
help
Enabled reading/writing the bootcount in a DM i2c eeprom device.
The wrapper device is to be specified with the compatible string
'u-boot,bootcount-i2c-eeprom' and the 'i2c-eeprom'-property (a phandle
pointing to the underlying i2c eeprom device) and an optional 'offset'
property are supported.

bool "Enable Bootcount driver for PMIC PFUZE100"
depends on DM_PMIC_PFUZE100
help
Enable support for the bootcounter using PMIC PFUZE100 registers.
This works only, if the PMIC is not connected to a battery.
config DM_BOOTCOUNT_SPI_FLASH
bool "Support SPI flash devices as a backing store for bootcount"
depends on DM_SPI_FLASH
help
Enabled reading/writing the bootcount in a DM SPI flash device.
The wrapper device is to be specified with the compatible string
'u-boot,bootcount-spi-flash' and the 'spi-flash'-property (a phandle
pointing to the underlying SPI flash device) and an optional 'offset'
property are supported.
config BOOTCOUNT_MEM

help
Enabling Memory based bootcount, typically in a SoC register which
is not cleared on softreset.

config DM_BOOTCOUNT_SYSCON
bool "Support SYSCON devices as a backing store for bootcount"
select REGMAP
select SYSCON
help
Enable reading/writing the bootcount value in a DM SYSCON device.
The driver supports a fixed 32 bits size register using the native
endianness. However, this can be controlled from the SYSCON DT node
configuration.
Accessing the backend is done using the regmap interface.
config DM_BOOTCOUNT_ZYNQMP

This option enables packing boot count magic value and boot count
into single word (32 bits).
