Because timestamp is declared as `static', we needn't initialize
it by writing it a zero. If we do it before relocate_code, we
will write into a flash address(0xbfc0).

fix warnings when building mips64, we define CONFIG_MIPS64 in config file.
And this macro decides size_t.

As so far, U-Boot has already supports mips32. But there are some
differences between mips64 and mips32. Such as different ABI, different
output format. so this patch adds mips64 support.
I use cross compiler from clfs and build U-Boot like this:
