60 LONG_MPY upgrade. This is part of swapping out the LDIHI instruction for a
MPY, and the MPYS and MPYU instructions for MPYSHI and MPYUHI respectively.		 dgisselq 3077d 23h /
59 Simplified logic. dgisselq 3077d 23h /
58 Bug fix: the UART can now be reconfigured post-boot without a BREAK condition. dgisselq 3077d 23h /
57 Fixed the TX/RX addresses so that they match the documentation: TX first, then
RX.		 dgisselq 3085d 23h /
56 Brings code in line with the OpenCores core: parameterizes the reload value,
and the number of bits in the timer.		 dgisselq 3085d 23h /
55 Updated copyright notice. dgisselq 3085d 23h /
54 Updated copyright notice. dgisselq 3085d 23h /
53 Added a touch of error checking. dgisselq 3125d 23h /
52 This brings the XuLA2-LX25 SoC up to speed with the rest of the ZipCPU, and
prepares it for the 32x32 bit multiply instruction set change.		 dgisselq 3125d 23h /
51 Lots of bug fixes. The ugliest were in the prefetch cache, where instructions
from one cache line were being issued as valid in another. Other fixes include
pipeline fixes so that LOD (Rx),Rx; LOD(Rx),Rx works, and more. Finally, the
decode was adjusted so that brev no longer affects the flags.		 dgisselq 3135d 22h /
50 Updates to fix some broken early branching code, both in idecode and pfcache. dgisselq 3145d 00h /
49 Added some documentation to make the read and write calls easier to understand. dgisselq 3154d 01h /
48 Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ...		 dgisselq 3156d 02h /
47 Fixes the "NAN" clocks/second output, as well as making input timing come closer
to a realistic timing. (I actually don't know what timing the JTAG port is
providing, but ... the new timer is closer.)		 dgisselq 3156d 02h /
46 This is a bug fix release--fixing the bug that kept dumpsdram.cpp/wbsdram.v
from working when long pipelined reads were interrupted by the necessity of
a pair of refresh cycles.		 dgisselq 3156d 02h /
45 Minor cosmetic change, eliminates a warning in Xilinx's XISE but offers no
functional difference.		 dgisselq 3159d 22h /
44 NELM parameter adjusted to reflect the maximum number of lines the compressed
scope can handle: 31, not 32.		 dgisselq 3159d 22h /
43 Commentary changes only, no substance. dgisselq 3159d 22h /
42 Minor changes. dgisselq 3159d 22h /
41 Bug fix. This was preventing dumpsdram from accurately reading back what
had been written to the RAM earlier.		 dgisselq 3159d 22h /
