ARM: add relocation support
!! This breaks support for all arm boards !!
To compile in old style, you must define
CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile
with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board"
!! This define will be removed soon, so convert your
board to use relocation support
Portions of this work were supported by funding from
the CE Linux Forum.
