  • This patch updates the maple bus to support asynchronous block reads
    and writes as well as generally improving the quality of the code and
    supporting concurrency (all needed to support the Dreamcast visual
    memory unit - a driver will also be posted for that).

    Changes in the bus driver necessitate some changes in the two maple bus
    input drivers that are currently in mainline.

    As well as supporting block reads and writes this code clean up removes
    some poor handling of locks, uses an atomic status variable to serialise
    access to devices and more robusly handles the general performance
    problems of the bus.
