[PATCH 08/14] ARM: ux500: make debug macro stand-alone

Linus Walleij linus.walleij at stericsson.com
Fri Apr 5 10:22:50 EDT 2013


From: Linus Walleij <linus.walleij at linaro.org>

This pushes the knowledge of physical addresses down into
the debug macro so we can get rid of the <mach/hardware.h>
dependency.
