This patch set adds support for calling panic() before stdio is initialized. At present this will just hang with little or no indication of what the problem is.
A new board_panic_no_console() function is added to the board API. If provided by the board it will be called in the event of a panic before the console is ready. This function should turn on all UARTS and spray the message out if it possibly can. This is somewhat related to the Graeme's pre-console buffer patch, which is why I am sending it for comment now.
