[PATCH] ARM: compressed/head.S: use addruart properly

From: kpark3469
Date: Tue Aug 26 2014 - 04:30:48 EST


From: Sahara <keun-o.park@xxxxxxxxxxxxx>

This patch fixes compile error in compressed/head.S, when DEBUG
is defined. Since addruart macro accepts 3 params, rp, rv, and tmp,
loadsp macro also needs to be fixed. Or you will meet the following
error messages:
Error: ARM register expected -- `mov ,#(5<<1)'
Error: shift expression expected -- `add r3,r3,'
