.. _devicetree_binding_mtd_partition:
Representing flash partitions in devicetree
===========================================
In addition to the upstream binding, another property is added:
Optional properties:
* ``partuuid``: The global partition UUID for this partition.
For GPT partitions, the partuuid is the 16-byte GPT Partition UUID (e.g.
``de6f4f5c-c055-4374-09f7-8c6821dfb60e``).
For MBR partitions, the partuuid is the 4-byte disk identifier
followed by a dash and the partition number (starting with 1, e.g.
``c9178f9d-01``).
The partuuid is case-insensitive.
Additionally, barebox also supports partitioning the eMMC boot partitions if
the partition table node is named appropriately:
* ``partitions`` : user partition
* ``boot0-partitions`` : boot0 partition
* ``boot1-partitions`` : boot1 partition
Examples:
.. code-block:: none
/ {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
state_part: state {
partuuid = "16367da7-c518-499f-9aad-e1f366692365";
};
};
};
emmc@1 {
boot0-partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
barebox@0 {
label = "barebox";
reg = <0x0 0x300000>;
};
};
};
