Otherwise more complicated uart configuration won't be possible. We can use r1 for tmp register for both head.S and debug.S. NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files. That can be done with: $ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/" arch/arm/*/include/*/debug-macro.S Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
