From 3f7f6b8592ac9cd33117913310b9e6dbcc86acac Mon Sep 17 00:00:00 2001 From: Roy Zang Date: Thu, 9 Jun 2011 11:30:52 +0800 Subject: powerpc/85xx: Add basic support for P1023RDS board The P1023RDS board is the reference board for the P1023 SoC. Add support for booting it from NOR or NAND, with fixed 2G of DDR, PCIe, UART, I2C, etc. Signed-off-by: Roy Zang Signed-off-by: Haiying Wang Signed-off-by: Chunhe Lan Signed-off-by: Lei Xu Signed-off-by: York Sun Signed-off-by: Kumar Gala --- nand_spl/board/freescale/p1023rds/Makefile | 132 ++++++++++++++++++++++++++ nand_spl/board/freescale/p1023rds/nand_boot.c | 99 +++++++++++++++++++ 2 files changed, 231 insertions(+) create mode 100644 nand_spl/board/freescale/p1023rds/Makefile create mode 100644 nand_spl/board/freescale/p1023rds/nand_boot.c (limited to 'nand_spl') diff --git a/nand_spl/board/freescale/p1023rds/Makefile b/nand_spl/board/freescale/p1023rds/Makefile new file mode 100644 index 0000000000..168e868641 --- /dev/null +++ b/nand_spl/board/freescale/p1023rds/Makefile @@ -0,0 +1,132 @@ +# +# Copyright 2010-2011 Freescale Semiconductor, Inc. +# +# 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.
