From 4db896236cdac37db17b215ba3ff2d2701bddb49 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20Bie=C3=9Fmann?= Date: Fri, 6 Feb 2015 23:06:44 +0100 Subject: [PATCH] avr32: use generic gd->start_addr_sp MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Before avr32 had an extra storage for stack end to have a nice stack printout on exception. Remove this extra storage and use generic gd->start_addr_sp instead.
