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. |

Adds register values for the SD-Card registers. |

| 80 |
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). |

Adds 'bench' and 'sw' targets, and automatically builds them (now). |

Comments out the line that caused a compiler warning--setting an unused
variable. Code should be better as a result. |

Adds register names and values for the SD card interface. |

Now tries to avoid reading from the stack if the stack addresses are already
known to be bad. That way, the debugger tries to preserve any bus error address
already on the buserr device. |

2940d 23h |
/xulalx25soc/trunk/ |
| 75 |
Added simulation capability for the SD-Card, as well as debugging output for the
DMA. (The SD-Card debug may not be fully featured, yet, but it has gotten me
to where I can talk to the card.) |

2940d 23h |

Adds the SD-card capability, and connects the debug wires to/from the uartdev
in case it needs to be debugged. |

Sets XULA25 as the default. |

Needed to play with subtle timing to get this to build. Expect me to play
with these two clock numbers more. |

Cosmetic (minor) update. |
dgisselq |
2941d 00h |
/xulalx25soc/trunk/ |
| 69 |
Massive logic simplification. This is also the first (verified) working
version. |

Fixes the debug ack line, so it no longer acks when there isn't a dbg_stb.
Fixed the multiply option parameter, so it sets a 3-clock multiply properly.
Adjusted the watchdog timer so that it now produces a timer that doesn't
reload--since this is pointless for a watchdog. Finally, connects a reset
line to the DMA, to make certain that resetting the CPU will also reset any
ongoing DMA operation. |

Simplifies logic, and guarantees that the minimum set value will always
produce an int. For example, if the count was X before, setting X-1 wouldn't
produce an interrupt since it had passed. Now it produces an interrupt, and
keeps the next interrupt valid. |

Simplified logic (barely). |

/xulalx25soc/trunk/ |
| 65 |
Makes the auto-reload feature a parameterized (generic) feature, so the same
code will work for both auto-reloadable and non-autoreloadable (i.e. watchdog)
timers. |

First (verified) working version. |

| 62 |
Removed the pipe logic from the non-pipelined version, and made the NOOP a
specific ALU instruction so that the PC is always properly updated. |
