59 /* Boolean set by platform if PIO accesses are suppored while _IO_BASE
61 * set when the platform supports "special" PIO accesses via a non memory
69 #error CONFIG_PPC_INDIRECT_{PIO,MMIO} are not yet supported on 32 bits
287 * top of MMIO addresses (not PIO, those have to cope the hard way).
302 * For PIO, there is a separate CONFIG_PPC_INDIRECT_PIO which makes
303 * all PIO functions call through a hook.
477 * PCI PIO and MMIO accessors.
480 * On 32 bits, PIO operations have a recovery mechanism in case they trigger
543 * handling of the IO base for PIO.
548 * Note that PIO operations are always defined in terms of their corresonding
551 * possible to hook directly at the toplevel PIO operation if they have to
919 * which needs some additional definitions here. They basically allow PIO
