U-Boot environment device
=========================
This driver provides a unified device exposing U-Boot environment
varaible data, sans the low-level parts. Resulting device is intended
to be used with corresponding filesystem driver to expose environment
data as a filesystem.
Required properties:
* ``compatible``: should be ``barebox,uboot-environment``
* ``device-path``: phandle of the partition the device environment is
on (single partiton configuration)
* ``device-path-0`` and ``device-path-1``: phandle of the partition
the environment is on (redundant configuration)
Example:
.. code-block:: none
environment {
compatible = "barebox,uboot-environment";
device-path-0 = &uboot_env_0;
device-path-1 = &uboot_env_1;
};
&usdhc4 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
uboot_env_0: partition@c0000 {
label = "uboot-environment-0";
reg = <0xc0000 0x4000>;
};
uboot_env_1: partition@cc800 {
label = "uboot-environment-1";
reg = <0xcc800 0x4000>;
};
};
};
