PCI on Lite5200/Icecube, known issues?

PCI on Lite5200/Icecube, known issues?

[Wolfgang Grandegger]

Hello,

The access to PCI memory space does not to work (I allways read 0xff) on 
my Icecube-Eval-Board. Are there any known issues/bugs with using the 
PCI on the Lite5200/Icecube board with 2.6.23? Has it been tested? I 
realized, that CONFIG_PCI is not set in the default configuration.

Thanks,

Wolfgang.

arch/ppc or arch/powerpc?

I'm not a PCI expert, but I just fired up my Lite5200 with a couple of
eth adapters plugged in and the devices are usable.  This is a
2.6.24-rc1 arch/powerpc kernel.

Cheers,

I'm using a 2.6.23 arch/powerpc kernel. And my eepro100 card does not 
work either:

e100: probe of 0000:00:18.0 failed with error -11

It looks like that 2.6.23 needs some more patches.

Thanks.

Wolfgang.

Indeed, it works with 2.6.24-rc1:

e100: eth0: e100_probe: addr 0xa0000000, irq 16, MAC addr 00:0e:0c:74:8c:f2

Okay, when I get a chance I'll try 2.6.23 on my lite5200
