4af7a27d87 Have linux booting. Not sure about uart, but uart is now part of the ILA and I can see TX changing. 2021-11-12 17:37:07 -06:00

b8572d6a2a Changed several things. 
Removed the need to use async flip flops in SDC.
Added arrs, a synchronizer for reset.
I think this works with the real FPGA hardware.
The last build did not include this arrs but it worked.
