orpsocv2: correct build/par issue on Atlys board
From patch submission e-mail:
The first of the series is an issue that has been around since the
beginning (at least based on the svn log files) and traces its root to the
first Xilinx board supported by orpsocv2, the ML501. Apparently Makefile
for the final place-and-route process in all the builds contains a typo
which leads to the routing tool not using any timing constraint at all.

atlys: add 2-clock synchronizer chain for ddr2_calib_done
The signal ddr2_calib_done signal comes from the ddr2 clock domain,
while wb_req is treating it as if it came from wb_clk domain. As a
result the timing analysis tool assumed a worst case scenario of 5ns
between the two domains and the results were miserable.
While we can argue that this is a multi-cycle path, the fact is that
ddr2_calib_done feeds into multiple logic sinks and can potentially
cause meta-stability issue in the design. The solution is to add a
2-clock meta-stability filter to address both the timing problems and
the meta-stability concern.
