+ * hash_tester.c
+ * --------------
+ * This program sends several commands to the coretest_hashes subsystem
+ * in order to verify the SHA-1, SHA-256 and SHA-512/x hash function
+ * cores.
+ *
+ * Note: This version of the program talks to the FPGA over an EIM bus.
+ *
+ * The single and dual block test cases are taken from the
+ * NIST KAT document:
+ * http://csrc.nist.gov/groups/ST/toolkit/documents/Examples/SHA_All.pdf
