powerpc:Add support of SPL non-relocation
Current SPL code base has BSS section placed after reset_vector. This means they have to relocate to use the global variables. This put an implicit requirement of having SPL size = Memory/2. To avoid relocation: - Move bss_section within SPL range - Modify relocate_code() Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
