From c57cca255ce403fdfe77e7b040b578a29514da0b Mon Sep 17 00:00:00 2001 From: Steve Sakoman Date: Fri, 11 Jun 2010 20:35:26 -0700 Subject: ARMV7: Add support for TI OMAP4 Panda OMAP4 Panda is a reference board based on OMAP4430, an ARMV7 Cortex A9 CPU This patch adds basic support for booting the board. It includes i2c and mmc support. It assumes U-boot is loaded to SDRAM with the help of another small bootloader (x-load) running from SRAM. U-boot currently relies on x-load for clock, mux, and SDRAM initialization Signed-off-by: Steve Sakoman Signed-off-by: Sandeep Paulraj --- board/ti/panda/Makefile | 49 ++++++++++++++++++++++++++++++++++++++ board/ti/panda/config.mk | 32 +++++++++++++++++++++++++ board/ti/panda/panda.c | 61 ++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 142 insertions(+) create mode 100644 board/ti/panda/Makefile create mode 100644 board/ti/panda/config.mk create mode 100644 board/ti/panda/panda.c (limited to 'board/ti/panda') diff --git a/board/ti/panda/Makefile b/board/ti/panda/Makefile new file mode 100644 index 0000000..81e5469 --- /dev/null +++ b/board/ti/panda/Makefile @@ -0,0 +1,49 @@ +# +# (C) Copyright 2000, 2001, 2002 +# 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.
