Unfortunately there was not much effort spent yet to support the LM3s
series yet. So there is only a configuration file and a linker script

In general the kernel will start up on the LM3S, but only the kernel.
Any device driver have to be written from scratch.

I just though about doing this, but currently I could do this only as a
commercial project, as my spare time is limited.

I'd be happy to give you any assistance, wherever you need. I have two
LM3S boards here, so I can also help you with debugging.

Whatever you better like.
