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

You also need to change it in the target's auto.c or
cache_as_ram_auto.c, you'll need to change both the IO base and the
com port. They're usually defines at the start of the file that you
have to change.
