  SVN rev 203509 on 2010-02-05 03:20:47Z by neel
  
  Reimplement all functions to access the system control unit in C.
  
  The only reason we need to have the sb_load64() and sb_store64()
  functions in assembly is to cheat the compiler and generate the
  'ld' and 'sd' instructions which it otherwise will not do when
  compiling for a 32-bit architecture. There are some 64-bit
  registers in the SCD unit that must be accessed using 64-bit
  load and store instructions.
