37fb44f33e 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

805a37447c 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.

d0f0c94652 phy/model: Don't generate empty mem_*.init files 
When using the SDRAM PHY model without specified init data, the
generator still generates a bunch of $readmemh for each bank
reading mem.init, mem_1.init etc... all of which are 0-sized files.

This is cumbersome especially when using a standalone model in
an external project.

This is fixed by having the default bank_init be set to a list
of "None" rather than a list of empty lists.

If the --sim argument is passed, this generates a model using

Note: The data_width is set to 16 for now, which matches the
Arty. I haven't yet figured out how to extract that info from
the data we have in the .yml
