Minor cosmetic change, eliminates a warning in Xilinx's XISE but offers no
functional difference. |

NELM parameter adjusted to reflect the maximum number of lines the compressed
scope can handle: 31, not 32. |

Bug fix. This was preventing dumpsdram from accurately reading back what
had been written to the RAM earlier. |

This adds to dumpsdram the capability to run over a port, such as with
busmaster_tb. |

An attempt at a bugfix. We'll see if this works any better downstream. |

Updated to remove the build dependence upon ZipCPU. |

These fixes were necessary to get the SDRAM into a working simulation
capability. It is finally what it was supposed to be: cycle accurate. Sadly,
to do this, I did need to make a subtle change to rtl/wbsdram.v. (I was having
a problem with external input clocking in Verilator. This fixes it--but its
a Verilator only change--to rtl/wbsdram.v that is.) |

Updates the memory testing program to work successfully with the Gnu build
tools--particularly the GNU C-preprocessor from GCC and the GNU assembler from
Binutils. |

Bug fix: This sets as a positive voltage bias (not negative) the maximum
value of 0x07fff, where as the negative maximum value of 0x08000 properly
(now) reflects nearly ground--as one would desire. (Last time around I had
these backwards.) |

Oops -- the audio was wired audio first then the interrupt controller, not
the other way around. This adjusts regdefs to match what's on the chip. |

Just noticed that the timer was fixed on this. This change adjusts the
timer to support audio at a user selectable rate. |

A bug fix, although one that rearranges the bus. The first four I/O locations
have been adjusted. The new locations are reflected in wishbone.html. In
addition, the PWM and UART devices no longer create bus errors when accessed.
Finally, this version uses a `define XULA25 to determine whether or not to build
for the XuLA2-LX9 or the XuLA2-LX25. If defined, it will build for the
XuLA2-LX25. If not, for the XuLA2-LX9. The ideal location for this define
would be to place it into your Xilinx configuration, should you wish to build
for the LX25. |

This adds a vastly updated and superious ziprun capability to the repository.
ziprun now accepts ELF program files *only*, reads them, and places them onto
the board. This includes the ability, within the ELF file, of specifying
whether or not the data is sent to block ram, SD ram, or Flash, as well as
the ability of specifying the initial address. (Of course, that's a one time
thing--to always have the same initial address, set the address in
rtl/busmaster.v) |

Bug fix: the last_state register now correctly reflects all 5-bits of the state
machine. (Useful when detecting lockups ...) |
