The IPMMU module supports the MMU function and the PMB function. The MMU function provides address translation by pagetable compatible with ARMv6. The PMB function provides address translation including tile-linear translation. This is implementation of the MMU function. v3: - Rebased on 3.6-rc5. - Simplify configs. SHMOBILE_IPMMU is now selected by setting SHMOBILE_IOMMU. - Remove weak symbols. - Use drvdata to store private driver data. - Make a function for writing to a register of IPMMU. - Add a lock to accessing the tlb_enabled member. - Make unmap work correctly with size larger than map size. - Free L2 page table when 1MiB page is mapped or unmapped. - Add VEU devices as IP blocks on the ICB. v2: - Rebased on v3.6-rc1. - Make variable names clear. - Page table size can now be selected by config.
