A first capability for setting time, dawn, and dusk values using the keypad.
At this point, I now have a minimal capability for actually accomplishing
the entire task. It's not very robust, but if you get lucky it'll work. |

Fixed a small lint bug associated with the scope vs the compressed scope. |

Added a bootloader capability so that pieces of the program may be immediately
loaded into RAM. Further, the custom linker script, cmodram.ld, has been
added to dispatch object files to either FLASH or RAM. Finally, for those
items that were headed to RAM, their support files have been split between
RAM and FLASH code: kernel.c/ksetup.c, syspipe.c/pipesetup.c, etc. |

Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability. |

Converted timer B to be a non-reloadable watchdog timer. |

Made the ziptimer autoreload feature a parameter (dis)abled option. |

Fixed a bug which caused every instruction to be loaded/prefetched twice. |

Initial version of the ZipOS operating system construct(s). |

Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock. |

This linker description file acknowledges a .fixdata section which can be
used for debug data upon startup. This allows a startup function to write
all registers out, without destroying them or modifying them on the way. |

Addition of dumpuart.cpp to dump the UART transactions to a FILE (method of
debugging the board). FLASHDRVR and ZIPLOAD were also updated to handle
loading ELF files where the code is longer than a single block. |

Added a picture of the device pinouts to the specification. |

Modifications necessary to find some bugs, and to load the flash with an ELF
file. |

Bug fix. This release fixes several bugs associated with transitioning from
user mode to supervisor mode while running from flash memory. This also
rewires TIMER-B into a watch-dog timer, and adjusts the LED's to be an
indicator of interrupts and whether or not the CPU has stalled or not as well. |

Adds a new program and a new device: doorbell2 and the PmodCLS display. This
also includes a real-time clock simulator--since we couldn't fit it on the
board. |

Modified the loader so that it will load even if there are RAM variables
in the load, just as long as they aren't anything but zero. (The startup code,
however, doesn't clear memory to match--so be sure to initialize all variables.) |

Fixed a nasty parameter problem between toplevel and txuart. The UART
transmitter now both works (again), and properly generates the required
interrupts. This also finishes the fixes to the alternate toplevel file,
alttop.v, that should've been fixed in the last release. |

The UART and PWM audio now work. This includes the changes to make that
happen, as well as the source code for some UART and PWM demo programs. |

Runs on hardware now! Added proper pinouts, pipelined wishbone command
interface sufficient for loading the flash, a loader to load the flash,
and verified that they work. |

Added the capability to run ELF files natively, fully processing the ELF format. |
