This continues the updates to the wishbone-uart conversion. It fixes several
bugs within wbuexec, and pipelines the compression scheme. Further, the
read codeword was adjusted so that a read of 8 can be requested with six-bits,
rather than requiring 12. Likewise, the dependence upon the read of 8 on
incrementing the address pointer has been removed. All told, the design
builds for a 200MHz Artix-7, and it has been tested with the CMod-S6. (Writing
flash seems to be one of the most comprehensive tests ...) |

Minor documentation updates. |

Minor change. |

Minor, inconsequential changes. |

Mostly cosmetic changes. The Makefile now builds a couple more programs,
the documentation is better, etc. |

Updates to the flash driver drawn from the S6SoC project. |

Added a SDSPI scope, and defined which of the four scopes it points to.
(It uses the configuration scopes position, if the configuration scope isn't
defined.) |

Updated documentation. The documentation for these now also reflects that
these were drawn from an FPGA Library project, that is shared among many
FPGA builds. |

Fixed the `defines at the top so that this can be built without any CPU.
This was then used to measure the impact of the CPU on the entire build, as
you could now build with no CPU, and then with a CPU to compare. |

Includes updates so this can run at higher clocks speeds within an FPGA. |

Includes high-speed updates. rxuart and txuart will now run at 200MHz on
an Artix-7, so should not impact timing (any more) on the XuLA platform. |

made in 2016. |

Now accepts an SD-Card backing file, so that SD-Card reads *and* writes can be
tested. |

Added write capability to the SD-SPI simulator. |

Fixes a bug which had caused the device to die artificially and early, just
simply because the program connecting to the simulator shut its pipe down before
getting our last message. We now ignore this signal and continue. |

Fixes the problem whereby the master counters show when the user counters should
be showing and vice versa. Now the master counters show by default, together
with their correct labels. User counters are still available by pressing
'u' in the debugger, and the master counter display may be returned to by
pressing 'm' in the debugger. |

Fixes bugs associated with an overflow of write acknowledgements in the
receiver. This helps keep our accesses aligned. |

Reads and writes to the SD over SPI port now work. The card appears, as of now,
to be fully functional. |

Bug fixes, following the adf_ce logic combining ALU/DIVIDE/FPU pipeline logic
into one register, this fixes that logic so that instructions without their
condition fulfilled are still "executed" and marked as done. |

Fine tuning the `defines, so that you can build pipelined without pipelined
bus access and so forth. |

First version of the SD-SPI interface, with partial functionality. (No the
empty link that was here before.) |

First part of switching to proper sdspi.v, and not just the link. |

Fixes a bug in the LX9 build whereby the flash was never ever granted permission
to use the SPI port. |

Currently working version: contains both a working DMA controller as well as
a working (as far as I can tell) SD-Card controller (writes not yet tested). |
