[RFC 02/13] driver core: Introduce MMIO configuration

2021-02-26 Thread Nicolas Saenz Julienne
Some devices might inadvertently sit on buses that don't support 64bit MMIO access, and need a mechanism to query these limitations without prejudice to other buses in the system (i.e. defaulting to 32bit access system wide isn't an option). Introduce a new bus callback, 'mmio_configure(),' which
