Fixes a compiler warning about signed versus unsigned comparison, by forcing
the comparison to be signed. |

Made the SDCard support dependent upon a XULA25 macro, which is defined at the
top of the file. Remove the XULA25 macro definition, and this will build
assuming a XULA9 configuration. |

Added ZipBones to the list of dependencies, so this will (should) build
properly for the XULA9 as well as the XULA25. |

Lots of updates, mostly focused on getting the XuLA board and CPU able to pass
a comprehensive test suite. At this point, everything passes and logic usage
is down even. Among the few changes includes the "break" bit in the uCC
register, used to indicate a switch to supervisor mode occurred as a result
of a user break, and the ability for the supervisor to clear the instruction
cache. |

Fixed a problem whereby block RAM would be declared as a bus error on the
stack, even if the data was valid. |

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 ...) |

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 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. |
