+AMCC SoC SATA Support 
+
+This following is only for the 460ex support for Designware SATA core
+
+Required properties:
+- compatible : "amcc,sata-460ex".
+- reg : the first set defines SATA controller register, the second set
+        is for the AHB DMA controller for SATA.
+- interrupt-parent: UIC3
+- interrupts: one for SATA and one for the DMA
+
+Notes:
+The SATA is only available when the first PCIe port is disabled.
+
+Example:
+
+SATA0: sata at bffd1000 {
+	compatible = "amcc,sata-460ex";
+        reg = <4 0xbffd1000 0x800 4 0xbffd0800 0x400>;
+	interrupt-parent = <&UIC3>;
+	interrupts = <0 4       /* SATA */
+		      5 4>;     /* AHBDMA */
+};
+
