So, original patch is +config PCI_DOMAINS + def_bool y + depends on PCI && ARCH_CXXXXXX + But I removed the "&& ARCH_CXXXXXXX" before I provided the patch. Because ARCH_CXXXXXXX is not exist in ARM Linux kernel now (maybe it would be committed at someday) I traced other ARM platforms, some platforms like Marvell Orion5x seems has both PCI and PCIe host controller, Maybe they can use PCI domain to control their PCI/PCIe host controller. -------------- next part -------------- An HTML attachment was scrubbed...
