these atmel specific led stuff is basically for very early debug
(switching a LED after relocation, another one after board init, ..). It
also provides possibility to use it in assembler code sections e.g.
lowlevel_init.

I do not really care about that cause I normally use JTAG to debug early
code. The led switching at a specific stage could be done by one of the
other generic led drivers.

Beside that, I think for debugging early stage code without JTAG the
serial line is much better than a LED which can only provide two states.
Has anyone thought about that? Has anyone tried to add some
'early_printf' feature?

Best regards
