bootcount: add a new driver with syscon as backend

2021-08-22T09:04:52+00:00

The driver will use a syscon regmap as backend and supports both
16 and 32 size value. The value will be stored in the CPU's endianness.

boot counter values with DM enabled.

bootcount_ext: Add Ext4 build dependency

2020-06-02T21:27:04+00:00

This config option depends on EXT4 support.
If Ext4 write capability is not selected, it generate write error messages
and is unable to maintain boot counter.

bootcounter: add DM support for memory based bootcounter

2020-03-16T07:05:00+00:00

add DM/DTS support for the memory based bootcounter
in drivers/bootcount/bootcount.c.

Let the old implementation in, so boards which have
not yet convert to DM/DTS do not break.

bootcount: add a DM i2c eeprom backing store for bootcount

This driver allows the use of i2c eeprom device or partition as backing
store for boot counter values with DM enabled.

bootcount: add a DM RTC backing store for bootcount

2018-12-10T09:04:45+00:00

This implements a driver using a RTC-based backing store for the DM
bootcount implementation.  The node configuring this feature will be
compatible with 'u-boot,bootcount-rtc' and the underlying RTC device
shall be reference through the property 'rtc'. An offset into the RTC
device's register space can be provided through the 'offset' property.

Tested on a RK3399-Q7 on a Flamingo carrier board using the SRAM area
of the carrier board's RV3029 RTC.

bootcount: add uclass for bootcount

2018-12-10T09:04:44+00:00

The original bootcount methods do not provide an interface to DM and
rely on a static configuration for I2C devices (e.g. bus, chip-addr,
etc. are configured through defines statically).  On a modern system
that exposes multiple devices in a DTS-configurable way, this is less
than optimal and a interface to DM-based devices will be desirable.

This adds a simple driver that is DM-aware and configurable via DTS.
If ambiguous (i.e. multiple bootcount-devices are present) the
/chosen/u-boot,bootcount-device property can be used to select one
bootcount device.

Initially, this provides support for the following DM devices:
 * RTC devices

bootcount: Make bootcount magic configurable

2018-10-19T18:16:43+00:00

Add new Kconfig option, SYS_BOOTCOUNT_MAGIC, to select the boot
counter magic word. This can be useful ie. in case the entire
boot counter register is not usable.
