Instead of adding yet another implementation of the same code I would
like to see at least common code being used within an architecture;
for PowerPC, we already have different implementations in
"cpu/ppc4xx/cpu.c" and in "cpu/mpc86xx/cpu.c".

Not to mention that "cpu/arm920t/at91rm9200/reset.c" and
"cpu/blackfin/cpu.h" / "cpu/blackfin/reset.c" have such code, too.

Can we please come up with one common implementation?

Thanks.

Best regards,

Wolfgang Denk
