113 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.		 dgisselq 3053d 05h /xulalx25soc/trunk/rtl/ioslave.v
74 Adds the SD-card capability, and connects the debug wires to/from the uartdev
in case it needs to be debugged.		 dgisselq 3090d 23h /xulalx25soc/trunk/rtl/ioslave.v
31 A bug fix, although one that rearranges the bus. The first four I/O locations
have been adjusted. The new locations are reflected in wishbone.html. In
addition, the PWM and UART devices no longer create bus errors when accessed.
Finally, this version uses a `define XULA25 to determine whether or not to build
for the XuLA2-LX9 or the XuLA2-LX25. If defined, it will build for the
XuLA2-LX25. If not, for the XuLA2-LX9. The ideal location for this define
would be to place it into your Xilinx configuration, should you wish to build
for the LX25.		 dgisselq 3181d 02h /xulalx25soc/trunk/rtl/ioslave.v
18 Got the bitfile back up to speed at 80 MHz. dgisselq 3247d 03h /xulalx25soc/trunk/rtl/ioslave.v
9 Bug fixes, optimizations, etc. as part of building for an actual hardware
implementation. Most notably, the speed was lowered from 80MHz down to
76 MHz.		 dgisselq 3249d 01h /xulalx25soc/trunk/rtl/ioslave.v
2 A very first, albeit incomplete, build. dgisselq 3251d 22h /xulalx25soc/trunk/rtl/ioslave.v
