or1200_genpc: fix ipcu_cycstb_o generation
In some circumstances the CPU is still waiting for the lsu to finish
while in a pre branch state. However, ipcu_cycstb_o is set and the cycle
starts with the wrong address on the iwb bus (the one before the
branched address).
This fixes this issue.

or1200: Fix for cache bug related to first_{hit|miss}_ack
Under certain circumstances, when first_hit_ack and
first_miss_ack is asserted at the same time, cache data
would wrongly be overwritten with bus data.

or1200: l.lws support
Using the l.lws instruction doesn't work currently.
It simply skips the instruction. No exception or reaction.
The patch attached simply duplicates the behaviour of
l.lwz for l.lws.

OR1200 debug unit: prevent deadlock when trap instruction stalls
As per mailing list post <20120925160925.5725e06f@latmask.vernier.se>,
the debug unit could deadlock with the instruction decoder if the trap
instruction is held back by a pipeline stall. This change prevents that.
The problem can be reproduced by placing a breakpoint at an unfavorable
position with instruction cache enabled. In our test, this occurred
with or1200-cbasic when placing a breakpoint at test_bss using gdb, but
this is dependent on such factors as cache parameters and compilation
result. |

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.
