From 1f4d53260ec6f8f122aed75cce7c757d97a551e0 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Delgado Date: Tue, 21 Oct 2008 18:29:46 +0200 Subject: ppc4xx: Generic architecture for xilinx ppc405(v3) As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Stefan Roese --- board/xilinx/ppc405-generic/.gitignore | 1 + board/xilinx/ppc405-generic/Makefile | 60 +++++++++ board/xilinx/ppc405-generic/config.mk | 25 ++++ board/xilinx/ppc405-generic/u-boot-ram.lds | 134 +++++++++++++++++++ board/xilinx/ppc405-generic/u-boot-rom.lds | 144 +++++++++++++++++++++ .../xilinx/ppc405-generic/xilinx_ppc405_generic.c | 59 +++++++++ board/xilinx/ppc405-generic/xparameters.h | 36 ++++++ 7 files changed, 459 insertions(+) create mode 100644 board/xilinx/ppc405-generic/.gitignore create mode 100644 board/xilinx/ppc405-generic/Makefile create mode 100644 board/xilinx/ppc405-generic/config.mk create mode 100644 board/xilinx/ppc405-generic/u-boot-ram.lds create mode 100644 board/xilinx/ppc405-generic/u-boot-rom.lds create mode 100644 board/xilinx/ppc405-generic/xilinx_ppc405_generic.c create mode 100644 board/xilinx/ppc405-generic/xparameters.h (limited to 'board/xilinx/ppc405-generic') diff --git a/board/xilinx/ppc405-generic/.gitignore b/board/xilinx/ppc405-generic/.gitignore new file mode 100644 index 0000000000..b644f59941 --- /dev/null +++ b/board/xilinx/ppc405-generic/.gitignore @@ -0,0 +1 @@ +config.tmp diff --git a/board/xilinx/ppc405-generic/Makefile b/board/xilinx/ppc405-generic/Makefile new file mode 100644 index 0000000000..b56bb490a2 --- /dev/null +++ b/board/xilinx/ppc405-generic/Makefile @@ -0,0 +1,60 @@ +# +# (C) Copyright 2000-2006 +# Wolfgang Denk, DENX Software Engineering, wd@denx.de. +# +# (C) Copyright 2008 +# Ricardo Ribalda-Universidad Autonoma de Madrid-ricardo.ribalda@uam.es +# Work supported by Qtechnology http://www.qtec.com +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it 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.
