*******************************************************
*******    Test Application for SPI driver    *********
*******************************************************
*    This test sends bytes of the last parameter to   *
*    a specific SPI device. The maximum transfer      *
*    bytes are 4096 bytes for bits per word less than *
*    8(including 8), 2048 bytes for bits per word     *
*    between 9 and 16, 1024 bytes for bits per word   *
*    larger than 17(including 17). SPI writes data    *
*    received data from the user into Tx FIFO and     *
*    waits for the data in the Rx FIFO. Once the data *
*    is ready in the Rx FIFO, it is read and sent to  *
*    user. Test is considered successful if data      *
*    received = data sent.                            *
*                                                     *
*    NOTE: As this test is intended to test the SPI   *
*    device,it is always configured in loopback mode  *
*    reasons is that it is dangerous to send ramdom   *
*    data to SPI slave devices.                       *
