SH4 and SH4A are compatible. But some instructions are different from these. In Linux kernel, It is treated as a separate CPU, but for now, I think that there is no need to divide especially in the U-Boot. This removes CONFIG_SH4A definition from source code, SH4A is treated as SH4. And this fix white space. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
