Timur Tabi - July 25, 2011, 8:25 p.m.
Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.

CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file.  Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.

CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.

Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot).  All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.

README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

+		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,

+- 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
+		that this macro be defined via the _HIGH and _LOW macros:
+
+		#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
+		forced to a value that ensures that CCSR is not relocated.
