//  INFORMATION
//
//  The physical addresses for SoC chip selects are fixed, hence they are 
//  defined  in the CPU's common directory. The virtual addresses of the SoC 
//  chip selects are defined by the OEM and are configured in the 
//  platform's configuration directory by the file: 
//  .../PLATFORM/<NAME>/SRC/CONFIG/CPU_BASE_REG_CFG.H.
//
//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------
//  NAMING CONVENTIONS
//
//  CPU_BASE_MEM_ is the standard prefix for CPU chip selects.
//
//  Memory ranges are accessed using physical, uncached, or cached addresses,
//  depending on the system state. The following abbreviations are used for
//  each addressing type:
//
//      PA - physical address
//      UA - uncached virtual address
//      CA - cached virtual address
//
//  The naming convention for CPU base registers is:
//
//      CPU_BASE_MEM_<ADDRTYPE>_<SUBSYSTEM>
//
