Subject: [PATCH v2 0/4] OMAP:IOMMU:Add L1 and L2 cache flush
This patch series is second version to
- add a new cache maintenance api to flush L1 cache.
- flush both L1 and L2 caches from iommu whenever the pagetable memory
is updated.
Added the new api support for ARMv6 and ARMv7
based on the dma functions. The implementation of the
new api is based on the approach[1] discussed some time back.

These patches have been validated on Panda Board.
