From 639da5ee374ba8f070690bbd355ca30139ce145a Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Wed, 31 Aug 2011 22:55:46 -0400 Subject: ARM: add an extra temp register to the low level debugging addruart macro Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.
