+- CONFIG_SYS_CCSRBAR_DEFAULT:
+               Default (power-on reset) physical address of CCSR on Freescale
+               PowerPC SOCs.
+
+- CONFIG_SYS_CCSRBAR:
+               Virtual address of CCSR.  On a 32-bit build, this is typically
+               the same value as CONFIG_SYS_CCSRBAR_DEFAULT.
+
+               CONFIG_SYS_DEFAULT_IMMR must also be set to this value,
+               for cross-platform code that uses that macro instead.
+
+- CONFIG_SYS_CCSRBAR_PHYS:
+               Physical address of CCSR.  CCSR can be relocated to a new
+               physical address, if desired.  In this case, this macro should
+               be set to that address.  Otherwise, it should be set to the
+               same value as CONFIG_SYS_CCSRBAR_DEFAULT.  For example, CCSR
+               is typically relocated on 36-bit builds.  It is recommended

+
+               #define CONFIG_SYS_CCSRBAR_PHYS ((CONFIG_SYS_CCSRBAR_PHYS_HIGH
+                       * 1ull) << 32 | CONFIG_SYS_CCSRBAR_PHYS_LOW)

+- CONFIG_SYS_CCSRBAR_PHYS_HIGH:
+               Bits 33-36 of CONFIG_SYS_CCSRBAR_PHYS.  This value is typically
+               either 0 (32-bit build) or 0xF (36-bit build).  This macro is
+               used in assembly code, so it must not contain typecasts or
+               integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSRBAR_PHYS_LOW:
+               Lower 32-bits of CONFIG_SYS_CCSRBAR_PHYS.  This macro is
+               used in assembly code, so it must not contain typecasts or
+               integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSR_DO_NOT_RELOCATE:
+               If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
