This is mostly useful for debugging the early boot process. Often boards can provide some low-level code that outputs a character on some debug port prior to passing the early setup code. Allow boards to implement an early_putc() function that will be used to redirect printf() and friends to this debug port until the proper console becomes ready.

Dumb question, shouldn't this plug into the DEBUG_UART stuff Simon did that's already merged?
