PATCH 1/1 Make STANDALONE_LOAD_ADDR configurable per board

Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

Note that some architectures (blackfin, coldfire, mips, sh, sparc) misuse the CONFIG_STANDALONE_LOAD_ADDR variable to not only specify the load address (as the name suggests), but also to supply additional linker options:

arch/blackfin/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x1000 -m elf32bfin arch/m68k/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x20000 -L $(clibdir) arch/mips/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x80200000 -T mips.lds arch/sh/config.mk:CONFIG_STANDALONE_LOAD_ADDR += -EB arch/sparc/config.mk:CONFIG_STANDALONE_LOAD_ADDR ?= 0x00000000 -L $(gcclibdir) -T sparc.lds

Please clean this up! Thanks -- wd
