The utility builds on the extended command protocol recently introduced in the EC and allows to test implementation of various cryptographic primitives available on CR50. This patch brings in the ftdi_spi_tpm.c and mpsse.c from the AOSP trunksd package. mpsse.c has been modified to limit its feature set (no i2c or bigbang support, only SPI0 mode), and ftdit_spi_tpm.c has been modified to properly present binary strings to the Python swig wrapper. The crypro_test.xml file includes descriptions of the tests to perform on the target. Most of its contents other than the first crypto_test element are borrowed from NIST AES test vectors set. See file header for description of the contents format. The actual test command is the tpmtest.py. When started it establishes connection with the device, and then reads test vectors from crypto_test.xml and executes them one at a time. Starting the test program with the -d command line argument enables debug output sent to the console. There are some other programs in ./extras which use the mpsse.c from AOSP, they will have to be modified to use the local copy.
