SWIOTLB support found in arch/powerpc/Kconfig

The configuration item CONFIG_SWIOTLB:

Help text

Support for IO bounce buffering for systems without an IOMMU. This allows us to DMA to the full physical address space on platforms where the size of a physical address is larger than the bus address. Not all platforms support this.

found in arch/x86/Kconfig

The configuration item CONFIG_SWIOTLB:

Help text

Support for software bounce buffers used on x86-64 systems which don't have a hardware IOMMU. Using this PCI devices which can only access 32-bits of memory can be used on systems with more than 3 GB of memory. If unsure, say Y.
