barebox environment
===================
This driver provides an environment for barebox from the devicetree.
Required properties:
* ``compatible``: should be ``barebox,environment``
* ``device-path``: path to the device environment is on
Optional properties:
* ``file-path``: path to a file in the device named by device-path
The device-path is a multistring property. The first string should contain
a nodepath to the node containing the physical device of the environment or
a nodepath to a partition described by the OF partition binding.
The subsequent strings are of the form <type>:<options> to further describe
the path to the environment. Supported values for <type>:
``partname``:<partname>
This describes a partition on a device. <partname> can
be the label for MTD partitions, the number for DOS
partitions (beginning with 0) or the name for GPT partitions.
The file-path is the name of a file located in a FAT filesystem on the
device named in device-path. This filesystem will be mounted and the
environment loaded from the file's location in the directory tree.
Example::
environment@0 {
compatible = "barebox,environment";
device-path = &flash, "partname:barebox-environment";
};
environment@1 {
compatible = "barebox,environment";
device-path = &mmc, "partname:1";
file-path = "barebox.env";
};
