If you're asking whether "depends on ARM" can be removed for PCI_MVEBU, I don't know the answer. I do see that CONFIG_ARCH_MVEBU is mentioned in arch/arm64, which doesn't seem to set CONFIG_ARM. In any event, I would consider a change like that to be a separate patch. Here I just want to focus on CONFIG_OF. Bjorn ^ permalink raw reply [flat|nested] 20+ messages in thread

And because ARCH_MVEBU means "32-bit mvebu OR 64-bit mvebu" there is additional "depends on ARM" to filter-out 64-bit mvebu. So _architecture_ dependency based on intention should be: (ARCH_MVEBU && ARM) || ARCH_DOVE || COMPILE_TEST But because there is no 64-bit Dove, it has same meaning as moving ARM from inner conjunction to outer. I do not know which syntax is better. So choose what you prefer (current version or some modification). > In any event, I would consider a change like that to be a separate > patch.
