New project, litehm2: a hostmot2 port to linsn rv901t

Is there any massively insurmountable reason that this project wouldn't work with a Trion T20 FPGA? I did notice that SRAM was mentioned in a previous post, does this require an external SRAM chip or does it use internal FPGA resources?

It should be possible since the HM2 source that supports the T20
is available. I would expect that the on-chip RAM is sufficient

I did notice that in litehm2.py there are imports for "M12L64322a" and "GENSDRPHY", though they do not appear to be used anywhere. I just wanted to confirm that they aren't required for functionality. 

How do I use two 901T boards connected to the switch at the same time?
In addition to setting the IP address of the card 10.10.10.10 and 10.10.10.11 , how does the HAL know that it is the only IO pin

You load the driver with multiple ip addresses specified
The hal pins/parameters will have different board numbers.

Its also important with multiple cards to use the read-request function
so that the second card does not have wait for the first card to respond
before its read data request is sent.
