From 56892fc475d61a5e6bfb912098dca8975ecf9b94 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sun, 16 Jun 2013 17:12:37 +0300 Subject: AMD southbridges: Move HAVE_HARD_RESET MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All 3 boards with AGESA_HUDSON had HAVE_HARD_RESET with the reset.c file already placed under southbridge/. All 15 boards with CIMX_SBx00 had HAVE_HARD_RESET with functionally identical reset.c file under mainboard/. Move those files under respective southbridge/.
