From 0c909551f88c0d92a919ff70127df7b33cdd473d Mon Sep 17 00:00:00 2001 From: Robin Getz Date: Mon, 21 Dec 2009 18:40:42 -0500 Subject: [PATCH] kgdb: add default generic stubs The default kgdb functions can be implemented with common U-Boot functions, so rather than force everyone to copy & paste these things, create a set of weak stubs.
