+* AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains "calxeda,hb-ahci" or "snps,spear-ahci"
+- interrupts : <interrupt mapping for SATA IRQ>
+- reg : <registers mapping>
+
+Example:
+ sata@ffe08000 {
+ compatible = "calxeda,hb-ahci";
+ reg = <0xffe08000 0x1000>;
+ interrupts = <115>;
+ };
