    This patch creates a generic implementation of early_ioremap() support
    based on the existing x86 implementation. early_ioremp() is useful for
    early boot code which needs to temporarily map I/O or memory regions
    before normal mapping functions such as ioremap() are available.

    Some architectures have optional MMU. In the no-MMU case, the remap
    functions simply return the passed in physical address and the unmap
    functions do nothing.
