Log:
  MFC r256753
  
  MFP4: 1136252
  
  Add an option ATSE_CFI_HACK to allow memory mapped CFI devices to have
  their address range allocated sharable so that atse(4) can find it's
  Ethernet address in the expected location.
  
  We intend to remove this hack once the BERI platform has a loader.
