      sh: maple: Support block reads and writes. · b233b28e
      Adrian McMenamin 提交于
      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.
