The generic code can contain a macro wit the "straight" code which can be overridden in var_io.h or var_io_devs.h. > - DSPI - Karl had written a DSPI driver.

Yes sometimes you need some more efficient. But standard driver opens opportunity for some standard devices: MMC card, SPI Flash memory, even Ethernet.
