* Compact Flash

The Cavium Compact Flash device is connected to the Octeon Boot Bus,
and is thus a child of the Boot Bus device.  It can read and write
industry standard compact flash devices.

Properties:
- compatible: "cavium,ebt3000-compact-flash";

  Compatibility with many Cavium evaluation boards.

- reg: The base address of the CF chip select banks.  Depending on
  the device configuration, there may be one or two banks.

- cavium,bus-width: The width of the connection to the CF devices.  Valid
  values are 8 and 16.

- cavium,true-ide: Optional, if present the CF connection is in True IDE mode.

- cavium,dma-engine-handle: Optional, a phandle for the DMA Engine connected
  to this device.

Example:
	compact-flash@5,0 {
		compatible = "cavium,ebt3000-compact-flash";
		reg = <5 0 0x10000>, <6 0 0x10000>;
		cavium,bus-width = <16>;
		cavium,true-ide;
		cavium,dma-engine-handle = <&dma0>;
	};
