+Picochip picoXcell SPAcc (Security Protocol Accelerator) bindings
+
+Picochip picoXcell devices contain crypto offload engines that may be used for
+IPSEC and femtocell layer 2 ciphering.
+
+Required properties:
+ - compatible : "picochip,spacc-ipsec" for the IPSEC offload engine
+ "picochip,spacc-l2" for the femtocell layer 2 ciphering engine.
+ - reg : Offset and length of the register set for this device
+ - interrupt-parent : The interrupt controller that controls the SPAcc
+ interrupt.
+ - interrupts : The interrupt line from the SPAcc.
+ - ref-clock : The input clock that drives the SPAcc.
+
+Example SPAcc node:
+
+spacc@10000 {
+ compatible = "picochip,spacc-ipsec";
+ reg = <0x100000 0x10000>;
+ interrupt-parent = <&vic0>;
+ interrupts = <24>;
+ ref-clock = <&ipsec_clk>, "ref";
+};

+ * This is a SIMD SHA-1 implementation. It requires the Intel(R) Supplemental
+ * SSE3 instruction set extensions introduced in Intel Core Microarchitecture
+ * processors. CPUs supporting Intel(R) AVX extensions will get an additional
+ * boost.
+ *
+ * This work was inspired by the vectorized implementation of Dean Gaudet.
+ * Additional information on it can be found at:
+ * http://www.arctic.org/~dean/crypto/sha1.html
+ *
+ * It was improved upon with more efficient vectorization of the message
+ * scheduling. This implementation has also been optimized for all current and
+ * several future generations of Intel CPUs.
+ *
+ * See this article for more information about the implementation details:
