      drivers: add a driver for snoop control unit · c20c0525
      Vishnu Banavath authored
      
      
      The SCU connects one to four Cortex-A5/Cortex-A9 processors
      to the memory system through the AXI interfaces.
      
      The SCU functions are to:
      - maintain data cache coherency between the Cortex-A5/Cortex-A9
        processors
      - initiate L2 AXI memory accesses
      - arbitrate between Cortex-A5/Cortex-A9 processors requesting
        L2 accesses
      - manage ACP accesses.
      
      Snoop Control Unit will enable to snoop on other CPUs caches.
      This is very important when it comes to synchronizing data between
      CPUs. As an example, there is a high chance that data might be
      cache'd and other CPUs can't see the change. In such cases,
      if snoop control unit is enabled, data is synchoronized immediately
      between CPUs and the changes are visible to other CPUs.
      
      This driver provides functionality to enable SCU as well as enabling
      user to know the following
      - number of CPUs present
      - is a particular CPU operating in SMP mode or AMP mode
      - data cache size of a particular CPU
      - does SCU has ACP port
      - is L2CPRESENT
