  Initial implementation of a Vector Graphic HD/FD Disk Controller
  with Wishbone interface. See the PDF in /doc for more information
  about this controller.
  
  For now, the storage is implemented in FLASH memory, which is read-only
  to the controller. Also, the controller does not check (CRC) the disk
  sector data, like the original does. Instead, it inserts 00's where the
  CRC goes, to simulate a correctly checked CRC.
  
  I am able to boot CP/M 2.2 using this controller, with the vgboot.mcs image
  programmed into FLASH. See the diskimage/ directory.
