Oops! Working on that now.

Ah makes sense. running into a weird loop in trying to get this to work:

```
Traceback (most recent call last):
  File "./ulx3s85f.py", line 66, in <module>
    main()
  File "./ulx3s85f.py", line 57, in main
    **soc_sdram_argdict(args))
  File "./ulx3s85f.py", line 32, in __init__
    **kwargs)
TypeError: __init__() got multiple values for argument 'device'
```

This is with `device      = "LFE5U-85F",` if I comment out that line I get:
```
Traceback (most recent call last):
  File "./ulx3s85f.py", line 66, in <module>
    main()
  File "./ulx3s85f.py", line 57, in main
    **soc_sdram_argdict(args))
  File "./ulx3s85f.py", line 32, in __init__
    **kwargs)
  File "/home/colepoirier/workspace/litex-boards/litex_boards/targets/ulx3s.py",
line 85, in __init__
    platform = ulx3s.Platform(device=device, toolchain=toolchain)
  File "/home/colepoirier/workspace/litex-boards/litex_boards/platforms/ulx3s.py",
line 119, in __init__
    assert device in ["LFE5U-25F", "LFE5U-45F", "LFE5U-85F"]
AssertionError
```

lol oops... Was confused because both are ECP5...
