From 55dd4ba5413b14e8ee24058c89ac5c05376c331c Mon Sep 17 00:00:00 2001 From: Prafulla Wadaskar Date: Thu, 16 Jul 2009 20:58:00 +0530 Subject: Marvell Sheevaplug Board support Reference: http://plugcomputer.org/ http://openplug.org/plugwiki/index.php/Das_U-boot_plug_support This patch is tested for- 1. Boot from DRAM/NAND flash 2. File transfer using tftp 3. NAND flash read/write/erase 4. Linux kernel and RFS Boot from NAND 5. Enabled USB PHY init for kernel need 6. Boot from USB supported Note: to boot Kirkwood kernel with USB support, you should add "usb start" in the boot sequence Signed-off-by: Prafulla Wadaskar --- board/Marvell/sheevaplug/Makefile | 51 +++++++++++ board/Marvell/sheevaplug/config.mk | 25 ++++++ board/Marvell/sheevaplug/sheevaplug.c | 155 ++++++++++++++++++++++++++++++++++ board/Marvell/sheevaplug/sheevaplug.h | 41 +++++++++ 4 files changed, 272 insertions(+) create mode 100644 board/Marvell/sheevaplug/Makefile create mode 100644 board/Marvell/sheevaplug/config.mk create mode 100644 board/Marvell/sheevaplug/sheevaplug.c create mode 100644 board/Marvell/sheevaplug/sheevaplug.h (limited to 'board') diff --git a/board/Marvell/sheevaplug/Makefile b/board/Marvell/sheevaplug/Makefile new file mode 100644 index 0000000..e378b5b --- /dev/null +++ b/board/Marvell/sheevaplug/Makefile @@ -0,0 +1,51 @@ +# +# (C) Copyright 2009 +# Marvell Semiconductor +# Written-by: Prafulla Wadaskar +# +# 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.
