    Add a new 'sf mmap' function to show the address of a SPI offset, if the
    hardware supports it. This is useful on x86 systems.
    
    Cover-letter:
    sf: Add documentation and an 'sf mmap' command
    This little series adds documentation and a few other tidy-ups to the
    'sf' command.
    
    It also provides a way to access memory-mapped SPI via the command line.
