That's because so far all boards where support for the status LED has
been enabled fall intot his group. Feel free to add your own version.

This is not correct. There is a "status_led.c" file only in  the  CPU
directories  for  5xx, 8xx and 82xx CPUs. These are pretty similar as
far as the status LED is affected.

I think this should go to drivers/ .

But the current implementation is CPU dependend.
