This fixes the problem whereby the ZipCPU didn't properly access more than
5 word-sized function parameters. |

Minor updates to the orconf.pdf pre-conference slide. (Added the 'to be
revealed' line. |

An updated version of the intensive CPU test. This one runs from C, and
requires a UART port and a PIC, but can run quite successfully on multiple
SoCs that have been built with the ZipCPU internal to them. |

Updated the spec to reflect changes in the CC register: the user break
flag, and the ability to command a clearing of the instruction cache. |

Bugfix version. This fixes a problem whereby function addresses with offsets
were not properly calculated, together with properly setting up pcrelative
offsets when using the move function together with a label. |

Added a test to make certain that the arithmetic right shift was properly
propagating the high order bit. (The test works under verilator, but didn't
initially work in Xilinx -- thus a difference between the two.) |

CPU. |

Trimmed OR1K instruction set down from 219 instructions, to the minimum number
of 48. Thanks to Olof for helping identify the minimal set! |

Logic updates, and bug fix corrections to bring this in line with the current
XuLA2-LX25 SoC version. (i.e., the XuLA version was debugged and improved,
this update pushes those improvements to the mainline.) |

Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce. |

valid, or the whole is idle. |

Updated to match the new/updated multiply instructions. Of course, this is
still hand optimized and not compiled--so it's not really a true and proper
test (yet), but ... it's what I have. |
