From 6d550ddd129b18cf800eab604f74536754526cd8 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Mon, 1 Sep 2014 20:44:20 +0200 Subject: sparc: remove sparc64/sparcv9 code The sparc64/sparcv9 code is incomplete. Furthermore there is no real embedded hardware for sparc64 available, so better remove it until someone comes up with a complete port.
