From bb907ab51fd04255923b7ecf9dab352078808351 Mon Sep 17 00:00:00 2001 From: Richard Retanubun Date: Mon, 26 Oct 2009 14:19:17 -0400 Subject: MCF5271-only: Added a weak board_reset function to allow custom reset This patch adds a board_reset function to allow boards to specify their own custom reset sequence (e.g. resetting by timing out watchdog). Tested only on MCF5271, can be expanded if needed.
