RE: [ECOS] iq80310: pci_init_find_82559s() never returns

[Jing Luo <Jing at vicom dot com>]

I had the same problem. IQ80310 is plugged in a PC at 32bit/33MHz PCI bus.
I tured off S3-2.
After download Redboot RAM start version, it hangs after
pci_init_find_82559s().
For further debug, it hangs at pciwindow_mem_alloc().

Is this in a PC or backplane? We've heard of conflicts with the PC Bios
before - if it's in a PC make sure S3-2 is off.

Alternatively there are some fixes we've made to the iq80310 that may help
this, however they aren't public yet until eCos v2 (which is now being
actively worked on again!)
