Hi Stefano,

Thank you - no particular reason for you to notice it, but I thought I
would cc you. The original purpose was to get some sort of message out
of a board that fails very early (before console_init_f()). It is
useful when using an fdt, since if the fdt cannot be found it is nice
to print a friendly message somehow.

Regards,
Simon
