This adds simple console support to the PBL which makes it possible to print more complex messages in the PBL than just strings or hex numbers. For now puts_ll is used to print the messages, so it depends on CONFIG_DEBUG_LL which makes it more a debugging option. However, this could be extended later to get regular output from the PBL if desired. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
