-Generic TPL framework
-=====================
-
-Overview
---------
-
-TPL---Third Program Loader.
-
-Due to the SPL on some boards(powerpc mpc85xx) has a size limit and cannot
-be compatible with all the external device(e.g. DDR). So add a tertiary
-program loader (TPL) to enable a loader stub loaded by the code from the
-SPL. It loads the final uboot image into DDR, then jump to it to begin
-execution. Now, only the powerpc mpc85xx has this requirement and will
-implemente it.
-
-Keep consistent with SPL, with this framework almost all source files for a
-board can be reused. No code duplication or symlinking is necessary anymore.
-
-How it works
-------------
-
-There has been a directory $(srctree)/spl which contains only a Makefile. The
-Makefile is shared by SPL and TPL.
-
-The object files are built separately for SPL/TPL and placed in the
-directory spl/tpl. The final binaries which are generated are
-u-boot-{spl|tpl}, u-boot-{spl|tpl}.bin and u-boot-{spl|tpl}.map.
-
-During the TPL build a variable named CONFIG_TPL_BUILD is exported in the
-make environment and also appended to CPPFLAGS with -DCONFIG_TPL_BUILD.
-
-The SPL options are shared by SPL and TPL, the board config file should
-determine which SPL options to choose based on whether CONFIG_TPL_BUILD
-is set. Source files can be compiled for TPL with options chosen in the
-board config file.
-
-TPL use a small device tree (u-boot-tpl.dtb), containing only the nodes with
-the pre-relocation properties: 'bootph-all' and 'bootph-pre-sram'
-(see doc/develop/spl.rst for details).
-
-For example:
-
-spl/Makefile:
-LIBS-$(CONFIG_SPL_LIBCOMMON_SUPPORT) += common/libcommon.o
-
-CONFIG_SPL_LIBCOMMON_SUPPORT is defined in board config file:
-#ifdef CONFIG_TPL_BUILD
-#define CONFIG_SPL_LIBCOMMON_SUPPORT
-#endif
