Tested: serial port (well, 1 of them, for console of course), IDE, Ethernet,
USB OHCI, and Mini-PCI. Untested are VGA and audio (it's a Geode and I haven't
dug into using VSA or the alternatives), as well as PS/2 kbd. and mouse.
It is extremely stable under Fedora Core 5 and kernel 2.6.20. This winterm is
a great embedded system, if you don't need the VGA or audio. It's working well
enough to commit to the repository, I just need to read up on how to properly
create a new mainboard and target first.
One thing I'd like to investigate as well is initializing the IRQ router in LB.
I've seen some discussion about this in the past, and I've come to the
conclusion that for Geode GX1/CS5530 systems, it should be initialized in LB
rather than Linux. It also seems like some LB ports do this, and others do
not. Is there an official position on this from the core maintainers?
