Hi,
These set of patches is the 2nd attempt at an API for PIO drivers.
Following James' suggestion on a kmap-like API, the pio_* functions no
longer look like the dma_map_* API.
There are situations where the page structure isn't available (the USB
HCD drivers) and I introduced the pio_begin()/pio_end() functions that
take care of the cache flushing.
I added another example for the mmci.c driver that is currently using
flush_dcache_page().
Thanks.
