[coreboot] using COM2 on Geode GX-1 system (v2)?

[Jonathan Sturges]

Hi,
I have a perfectly working coreboot v2 image for a GX-1 target of mine, but when I tried to switch it from COM1 to COM2, I can't make it work.  I thought it would be as easy as updating TTYS0_BASE from 0x3f8 to 0x2f8 in Options.lb, but that doesn't work.  What's the trick to making this work?

thanks,
Jonathan
