-// Wishbone module for spi communications with an SD Card
-// The programming interface is simple -- 
-//      Write the desired clock divider to address 1 (should be 1 or higher)
-//      Status is in address 0.  A 1 indicates the last transaction is done and it is safe to
-//          send another
-//      Writing a byte to address 2 sends that byte over SPI.  When it is done, 
-//          status (addr 0) goes high again, and the received byte can be read from address 3.
