Configuring PCI w/ 44x

Configuring PCI w/ 44x

I have a question regarding configuring PCI with 44x.  Using 2.6.17-rc3 as
a reference, PCI_CONFIG is defined for the 44x defconfigs, and Kconfig is
not enabled to reflect/change the setting for 44x.  When I update
arch/ppc/Kconfig to enable configuring or not configuring PCI with 44x, and
then don't configure it, the kernel won't compile:

Shouldn't not configuring PCI be allowed/supported?

Hmm, you cannot disable PCI for 44x in the current 2.6. It's always 
enabled.

If you changed Konfig to be able to do so, why are you complaining 
here? It's not enough to just change Konfig, you have to modify Ocotea 
port as well. Look for example how this is handled for 85xx.

Patches are welcome.
