The linux_litex_demo doesn't make much sense

[mithro]

It is the output of LiteX -- this demo should be an example of running LiteX using the SymbiFlow tools.

There are some partial instructions here: https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/xc/xc7/tests/soc/litex/mini_ddr/README.md but I believe they are missing anything about the PLL parameters. Is the idea to convert this example to invoke LiteX once the PLL parameter issue has a solution?
