We do not have to define CONFIG_4xx in board config headers because it is defined in arch/powerpc/cpu/ppc4xx/config.mk. include/configs/JSE.h defines "CONFIG_4x", not "CONFIG_4xx". I believe it is a typo because "CONFIG_4x" is not used at all in other files. So, I also deleted "CONFIG_4x" in include/configs/JSE.h. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
