8bb3d51aad Added generate around the dtim preload. 
Added readme to explain FPGA.

3d829dbbd3 Fixed two issues. 
First the xci files already include the xdc constraints for each IP block. There is no need to include the xdc files explicitly.
Second the bidir buffer for the sd card was connected backwards.

517cae796c Fixed more constraint issues in fpga. 
Added back in the ILA.
Design does not work yet.  Stil having issues with order of automatic
clock and I/O constraint ordering.
Added back in the preload for the boottim.
