I guess this means "we support devices that can DMA, but are not coherent". right?
Yes, basically when _CCA=0.
So what about
ARCH_SUPPORT_CACHE_INCOHERENT_DMASince this is specific to ACPI _CCA, I just want to be clear with the naming.
How about directly using the architecture names here, this is inherently architecture specific, and it's more likely that if another architecture gets added in the future that it will have other requirements.
