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.

Raise illegal instruction exception when l.ror is not implemented
Instead of throwing an illegal instruction exception when the rotate
instructions are disabled (OR1200_ALU_IMPL_ROTATE is undefined), another
instruction (slr?) was executed instead.
This closes bug 97

ORPSoC: Merge display_arch_state tasks
or1200-monitor contains the tasks display_arch_state and display_arch_state_except which are almost identical. This patch merges these two tasks into one, with a parameter to specify whether it should print out "(exception)" or not

ORPSoC: Add paramers to or1200-monitor for setting name and path of log files
Two small patches in one to make or1200-monitor more useful outside of orpsocv2:
- Setting log path with a parameter allows more flexible directory layout
- if the plusarg "testcase" is set at runtime, this is used to set a unique
prefix for the log files. Plusargs are currently not used in orpsocv2, so if
it is not set, the name falls back to the value of the parameter
TEST_NAME_STRING. The value of the parameter is set to the define
`TEST_NAME_STRING in the test bench top levele to avoid any changes to the
orpsocv2 scripts. With this, we can get rid of `include test-defines in
or1200_monitor.v

sysc: avoid using orpsoc internal classes directly
The problem with using the internal classes directly is
that you have to use the internally generated name,
this in itself is perhaps not such a big issue, the issue
is that the internal name changes when the underlaying verilog
design changes.
This works around this by using the classes through the
top module, which is part of the external api. |

Execute trapped instruction after breakpoint is removed
Closes bug #104
When the instruction replaced by a trap instruction is restored by the
debugger, this instruction is not executed.
Proposed solution:
- Checked for a debug unstall condition plus a trap condition in
or1200_du(dbg_stall && |except_stop).
- Then, when this event occur, flush the entire pipeline (in or1200_ctrl) and
set the pc to npc in or1200_genpc(which is equal to the trapped instruction
address).

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.

Using the l.lws instruction doesn't work currently.
It simply skips the instruction. No exception or reaction.
