Updated the CPU and distribution in general to handle 8-bit bytes. |

/openarty/ |
| 49 |
Moved the location of the ZIPSYSTEM in memory, made the artyboard.h constants
more friendly and more complete, fixed two bugs in the CPU (jumps to breaks,
and s/w clearing of icache), added a NO_USERMODE option to the CPU, and more.
Rebuild any user programs before using this build. |

Greatly expanded the specification, including how to's, getting started guide,
register definitions, etc. |

Updated the flash, and the flash test bench, for Quad I/O read commands. |

| 44 |
Fixed the flash so that it now runs in 1) high speed (41MHz), and 2) that it
doesn't struggle to do read bursts. This should greatly speed up access time. |

Cleaned up the CPU memory documentation. |

Fixed up the CPU so that it passes a multiply test bench, in addition to the
CPU test. |

These updates bring the distribution along to the point where both the GPS
clock subsecond tracking, as well as the OLEDrgb controller now work. |

| 33 |
Fixed the network receive CRC and MAC checking, and added ip-checking and
minimum packet length checking to the receiver. |

Network transmit and MIG memory both work now, though the clock speed has
been dropped to 80.125MHz. |

Here's the memory pin list, necessary for running Xilinx's Memory Interface
Generator. |

The memory now works. However, the core speed has been lowered to 81.25MHz
to do this. The top level file is no longer fasttop.v, but toplevel.v. |

Here are the updates from the first (failed) attempt to try to integrate
the DDR3 SDRAM controller onto this board. |

Includes settings necessary for the Arty to load from flash builds, and to
reconfigure itself later. |

A useful script for programming the device, given that the current device
program includes a valid comms interface. |

Removed the OLED controller one additional clock from the bus. This was
necessary to maintain the 200MHz clock speed, especially given the growing
fanout of the device bus. |
