add bench directory with a first bench on arty board.
...
The aim is to create an automated hardware bench, control is done over Etherbone
(but could also be done over UARTBone, PCIe, USB, etc...) and various frequencies
are tested and BIOS logged.
It would also be useful to be able to recompile/reload BIOS in this bench to easily
test software changes and verify it works with various frequencies.
Can be tested with:
./arty.py --build --load
lxserver --udp
./arty.py --test

Add support for TDQS mode.
...
This adds an optional argument to add_electrical_settings() that can
enable the TDQS mode for x8 DDR3 modules. Normally this would be used
when mixing x4 and x8 modules (eg: heterogenous DIMMS), but it can
also workaround boards with missing or broken DM signals.
