Modified the LSU/IFU and caches to improve critical path. Arty A7 went from 15 to 17Mhz. I believe we can push all the way to 20+Mhz with relatively little effort. Along the way I'm fixing up the scripts build the linux images for the flash card.

Fpga does not correctly boot linux. I think the solution here is to revert out all substantive changes except for parameterization and then add them back in one at a time. This is necessary because the parameterization is not completed in one contiguous group of commits.

I think the fpga is building again, but the debugger script needs to be updated. For some reason the nets are not present despite being marked debug.

Improved constraints and set ddr3 voltage to correct 1.35V. This voltage is only for synthesis. However I'm concerned because the gui did not let me select 1.35V.

Found and fixed the major architecture issue with the mig 7 used in the arty a7 board.
...
mig 7 is completely different from the ddr4 mig in that the internal pll does not general the required clocks. An external mmcm is required to general two inputs clocks and the required user clock.

Realized we need a separate mmcm when using the mig 7 for ddr3 rather than the ddr4 mig. Go figure.
