    dm: Add support for register maps (regmap) · 6f98b750
    Simon Glass authored
    Add a simple implementaton of register maps, supporting only direct I/O
    for now. This can be enhanced later to support buses which have registers,
    such as I2C, SPI and PCI.
    It allows drivers which can operate with multiple buses to avoid dealing
    with the particulars of register access on that bus.
