branching for trace experiments
Switched to state-machine for MD bus
Make logread accept arguments
Added SDRAM clock-to-out constraint
Added tracing to loader utility
Some sanity-checks and README additions
Only use -t with -p
Renamed converters
Fixed mem-ctrl, so no need for constraint hacks. Also added sampling non-cart reads.
Use async write for release-from-reset, to avoid trace-buffer filling up
Added write tracing, and add mdAS to distinguish CPU from DMA cycles
