From 69b0634a4ee98c9791815600d43b99f626a952f3 Mon Sep 17 00:00:00 2001 From: Niklaus Giger Date: Thu, 17 Jan 2008 12:53:56 +0100 Subject: [PATCH] ppc4xx: netstal/common define routines used by all boards Added some routines used by all Netstal boards: - nm_bsp.c: - nm_show_print and - common_misc_init_r - set_params_for_sw_install. Very specific code to handle our SW installation procedure - fixed_sdram.c: Common routines for HCU4 (and upcoming) MCU25 boards to handle sdram initialization. - nm.h: Common header Signed-off-by: Niklaus Giger --- board/netstal/common/fixed_sdram.c | 105 ++++++++++++++++++++++++++++++ board/netstal/common/nm.h | 38 +++++++++++ board/netstal/common/nm_bsp.c | 128 ++++++++++++++++++++++++++++++++----- 3 files changed, 255 insertions(+), 16 deletions(-) create mode 100644 board/netstal/common/fixed_sdram.c create mode 100644 board/netstal/common/nm.h diff --git a/board/netstal/common/fixed_sdram.c b/board/netstal/common/fixed_sdram.c new file mode 100644 index 0000000..8082f60 --- /dev/null +++ b/board/netstal/common/fixed_sdram.c @@ -0,0 +1,105 @@ +/* + *(C) Copyright 2005-2008 Netstal Maschinen AG + * Niklaus Giger (Niklaus.Giger@netstal.com) + * + * This source code is free software; you can redistribute it + * and/or modify it in source code form under the terms of the GNU + * General Public License as published by the Free Software + * Foundation; either version 2 of the License, or (at your option) + * any later version. + * + * 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.
