From db2f721ffcf9693086a7e5c6c7015f2019e7f52e Mon Sep 17 00:00:00 2001 From: wdenk Date: Thu, 6 Mar 2003 00:58:30 +0000 Subject: * Patch by Rune Torgersen, 13 Feb 2003: Add support for Motorola MPC8266ADS board * Patch by Kyle Harris, 19 Feb 2003: patches for the Intel lubbock board: memsetup.S - general cleanup (based on Robert's csb226 code) flash.c - overhaul, actually works now lubbock.c - fix init funcs to return proper value * Patch by Kenneth Johansson, 26 Feb 2003: - Fixed off by one in RFTA calculation. - No need to abort when LDF is lower than we can program it's only minimum timing so clamp it to what we can do. - Takes function pointer to function for reading the spd_nvram. Usefull for faking data or hardcode a module without the nvram. - fix other user for above change - fix some comments. * Patches by Brian Waite, 26 Feb 2003: - fix port for evb64260 board - fix PCI for evb64260 board - fix PCI scan * Patch by Reinhard Meyer, 1 Mar 2003: Add support for EMK TOP860 Module * Patch by Yuli Barcohen, 02 Mar 2003: Add SPD EEPROM support for MPC8260ADS board --- board/emk/top860/Makefile | 40 ++++ board/emk/top860/flash.c | 490 ++++++++++++++++++++++++++++++++++++++ board/emk/top860/top860.c | 187 +++++++++++++++ board/emk/top860/u-boot.lds | 122 ++++++++++ board/emk/top860/u-boot.lds.debug | 132 ++++++++++ 5 files changed, 971 insertions(+) create mode 100644 board/emk/top860/Makefile create mode 100644 board/emk/top860/flash.c create mode 100644 board/emk/top860/top860.c create mode 100644 board/emk/top860/u-boot.lds create mode 100644 board/emk/top860/u-boot.lds.debug (limited to 'board/emk') diff --git a/board/emk/top860/Makefile b/board/emk/top860/Makefile new file mode 100644 index 0000000000..ef173d0366 --- /dev/null +++ b/board/emk/top860/Makefile @@ -0,0 +1,40 @@ +# +# (C) Copyright 2000 +# Wolfgang Denk, DENX Software Engineering, wd@denx.de. +# +# 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.
