Lots of bug fixes. The ugliest were in the prefetch cache, where instructions
from one cache line were being issued as valid in another. Other fixes include
pipeline fixes so that LOD (Rx),Rx; LOD(Rx),Rx works, and more. Finally, the
decode was adjusted so that brev no longer affects the flags. |

Updates to fix some broken early branching code, both in idecode and pfcache. |

Added some documentation to make the read and write calls easier to understand. |

Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ... |

Fixes the "NAN" clocks/second output, as well as making input timing come closer
to a realistic timing. (I actually don't know what timing the JTAG port is
providing, but ... the new timer is closer.) |

This is a bug fix release--fixing the bug that kept dumpsdram.cpp/wbsdram.v
from working when long pipelined reads were interrupted by the necessity of
a pair of refresh cycles. |

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.) |

A linker script, appropriate to the XuLA25-LX25 SoC. |

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. |
