4 Boards and FPGA SoC's which support the OpenRISC standard platform. The
5 platform essentially follows the conventions of the OpenRISC architecture
6 specification, however some aspects, such as the boot protocol have been defined
11 - compatible: Must include "opencores,or1ksim"
15 A "cpus" node is required. Required properties:
16 - #address-cells: Must be 1.
17 - #size-cells: Must be 0.
18 A CPU sub-node is also required for at least CPU 0. Since the topology may
19 be probed via CPS, it is not necessary to specify secondary CPUs. Required
21 - compatible: Must be "opencores,or1200-rtlsvn481".
23 - clock-frequency: The CPU clock frequency in Hz.
29 compatible = "opencores,or1200-rtlsvn481";
31 clock-frequency = <20000000>;
38 The bootloader may pass the following arguments to the kernel:
39 - r3: address of a flattened device-tree blob or 0x0.
