;;  Header: mx31_base_mem.h
;;
;;  This header file defines the Physical Addresses (PA) of
;;  the SoC chip selects and external memory assignments.
;;
;;  Provides memory map definitions specific to the MX31 SoC.
;;
;;------------------------------------------------------------------------------


;;-----------------------------------------------------------------------------
;;  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>
