* 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.
