Bootcount Configuration
|
|
This is the implementation of the feature as described in
|
|
https://docs.u-boot-project.org/en/latest/api/bootcount.html
|
|
|
|
Required Properties:
|
|
- compatible: must be "u-boot,bootcount-syscon".
|
|
- syscon: reference to the syscon device used.
|
|
- reg: contains address and size of the register and the location and size of the bootcount value.
|
|
The driver supports a 4 bytes register length and 2 and 4 bytes bootcount value length.
|
|
- reg-names: must be "syscon_reg", "offset";
|
|
|
|
Example:
|
|
...
|
|
syscon0: syscon@0 {
|
|
compatible = "sandbox,syscon0";
|
|
reg = <0x10 16>;
|
|
};
|
|
...
|
|
bootcount@0 {
|
|
compatible = "u-boot,bootcount-syscon";
|
|
syscon = <&syscon0>;
|
|
reg = <0x0 0x04>, <0x0 0x04>;
|
|
reg-names = "syscon_reg", "offset";
|
|
};
