Eagle 100 (Stellaris LM3S6918)

Hi, I was going to grab my SAM3 eval boards from the closet, but to make 
space for them on my desk I had to put away the Micromint Eagle 100 
board that was sitting there. Then got to thinking the Eagle 100 would 
be a really good board for eCos. It's a COTS board around a Stellaris 
LM3S6918 with a decent amount of I/O. I'm not an Ethernet guy, so I 
probably couldn't get networking going on the board, but could probably 
manage the rest of the port pretty quickly.

I looked at the existing Stellaris eCos port for the lm3s8xx, and 
thought to make a corresponding lm3s6xxx. But on closer inspection, I 
found 19 processors in the 6000 series, all with different memory sizes 
and I/O. The only thing they share in common is that they have Ethernet 
but not CAN. The 8000 series has Ethernet and CAN. The 5000 series has 
CAN and USB. And so on...

So the breakdown of the Stellaris series doesn't exactly mesh with eCos 
directory structure, since the chip internals may have more in common 
with chips across the different series than within it.

So I'm at a loss on how to proceed. Any advice?

Thanks,
Frank
