From f250f191f833b1f8ceb5e8e4324e0abdac66cfe4 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Wed, 23 Sep 2009 18:54:18 +0000 Subject: Looks like this should have become cpu init code after growing up. The remaining questions are: - Why was it never used? - Why is it in /src and not in /src/cpu/ppc? Given this is dead code and part of an unmaintained powerpc port, I consider removing it trivial. (The code really does not do much) Signed-off-by: Stefan Reinauer Acked-by: Stefan Reinauer git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4662 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/pmc/altimus/mpc7410/Config.lb | 15 ------ src/pmc/altimus/mpc7410/mpc7410.c | 81 ----------------------------- src/pmc/altimus/mpc7410/setup.c | 104 -------------------------------------- 3 files changed, 200 deletions(-) delete mode 100644 src/pmc/altimus/mpc7410/Config.lb delete mode 100644 src/pmc/altimus/mpc7410/mpc7410.c delete mode 100644 src/pmc/altimus/mpc7410/setup.c diff --git a/src/pmc/altimus/mpc7410/Config.lb b/src/pmc/altimus/mpc7410/Config.lb deleted file mode 100644 index 63b3383e31..0000000000 --- a/src/pmc/altimus/mpc7410/Config.lb +++ /dev/null @@ -1,15 +0,0 @@ -## -## CPU initialization -## -dir /cpu/ppc/mpc74xx - -## -## Include the secondary Configuration files -## -dir /northbridge/motrola/mpc107 - -## -## Build the objects we have code for in this directory. -## -object mpc7410.o -object setup.o diff --git a/src/pmc/altimus/mpc7410/mpc7410.c b/src/pmc/altimus/mpc7410/mpc7410.c deleted file mode 100644 index 98070c77c0..0000000000 --- a/src/pmc/altimus/mpc7410/mpc7410.c +++ /dev/null @@ -1,81 +0,0 @@ -/* - * This file is part of the coreboot project. - * - * Copyright (C) 2000 AG Electronics Ltd. - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
