  • c2c460f7c   iommu/shmobile: Add iommu driver for Renesas IPMMU modules ... Browse Code ยป

    This is the Renesas IPMMU driver and IOMMU API implementation.

    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 patch implements the MMU function.

    The iommu driver does not register a platform driver directly because:
    - the register space of the MMU function and the PMB function
    have a common register (used for settings flush), so they should ideally
    have a way to appropriately share this register.
    - the MMU function uses the IOMMU API while the PMB function does not.
    - the two functions may be used independently.
