Browse Source 
Pull ARM Renesas SoC cleanup, refactoring and more SMP support from Kevin Hilman:
 "Lots of cleanup and refactoring and some SMP additions for Renesas
  platforms.  Due to some inter-dependencies with other arm-soc
  branches, this Renesas stuff was separated out for sending after the
  other branches were merged.

  Highlights:
   - remove unused board support and cleanup of unused headers
   - refactoring of init and device registration
   - simplify IRQ initialization"
