FROMLIST: iommu: dma-iommu: use common implementation also on ARM architecture
This patch replaces ARM-specific IOMMU-based DMA-mapping implementation
with generic IOMMU DMA-mapping code shared with ARM64 architecture. The
side-effect of this change is a switch from bitmap-based IO address space
management to tree-based code. There should be no functional changes
for drivers, which rely on initialization from generic arch_setup_dna_ops()
interface. Code, which used old arm_iommu_* functions must be updated to
new interface.
To avoid build failed on ARCH arm,we mannually fix the following two files that
to use arch_set_dma_ops API
arch/arm/mach-highbank/highbank.c
arch/arm/mach-mvebu/coherency.c
