<p>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:<br>

Shouldn't not configuring PCI be allowed/supported?<br>
