* 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.
