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. |

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. |

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. |

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. |

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. |

Lots of bug fixes: After turning on XIP, and running in XIP mode, leaving XIP
mode turns it back off again, necessitating a new write to the VCon register.
Further, XIP mode starts in extended SPI mode, and only transfers in QSPI
mode for data. Finally, two new commands have been created: enabling the
SPI memory reset, and actually resetting the SPI memory. In general, these
are all better--as the EQSPI flash controller now works with these changes,
whereby it didn't really work without them before. |
