I've seen the same symptoms Sylvain described on the five Lite5200
boards that I have tried. Eepro100 network cards work fine, but the 3
brands of IDE cards I tried are not even visible in PCI config space.
U-boot doesn't see them and Linux doesn't see them, booted either from
dBUG or U-boot.
Actually, one Lite5200/IDE combo comes close. Parts of the IDE cards
PCI config info do read correctly sometimes. Different parts each time.
I think this is likely a hardware issue with Lite5200 boards.
