+* Microchip PIC32MZDA Platforms
+
+PIC32MZDA Starter Kit
+Required root node properties:
+ - compatible = "microchip,pic32mzda-sk", "microchip,pic32mzda"
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required. Required properties:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mti,mips14KEc".
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "mti,mips14KEc";
+ };
+ };
+
+Boot protocol
+--------------
+In accordance with Unified Hosting Interface Reference Manual (MD01069), the
+bootloader must pass the following arguments to the kernel:
+ - $a0: -2.
+ - $a1: KSEG0 address of the flattened device-tree blob.
