Prafulla Wadaskar prafulla at marvell.com
Mon Aug 24 19:33:59 CEST 2009


This patch adds type kwbimabe support for new mkimage core
For more details refer docs/README.kwbimage

This patch is tested with Sheevaplug board

Signed-off-by: Prafulla Wadaskar <prafulla at marvell.com>

Change log:
v2: updated as per review comments for v1
added len checks in checksum functions
added printable strings for each valid table entry
use of sccanf not changed since it offers return value for failure

v3: resolved merge issues on mkimage branch

+---------------------------------------------
+Kirkwood Boot Image generation using mkimage
+---------------------------------------------
+
+This document describes the U-Boot feature as it
+is implemented for the Kirkwood family of SoCs.
+
+The Kirkwood SoC's can boot directly from NAND FLASH,
+SPI FLASH, SATA etc. using its internal bootRom support.
+
+for more details refer section 24.2 of Kirkwood functional specifications.
+ref: www.marvell.com/products/embedded.../kirkwood/index.jsp
+
+Command syntax:
+--------------
+./tools/mkimage -l <kwboot_file>
+		to list the kwb image file details
+
+./tools/mkimage -n <board specific configuration file> \
+                -T kwbimage -a <start address> -e <execution address> \
+		-d <input_raw_binary> <output_kwboot_file>
+
+for ex.
+./tools/mkimage -n ./board/Marvell/openrd_base/kwbimage.cfg \
+                -T kwbimage -a 0x00600000 -e 0x00600000 \
+		-d u-boot.bin u-boot.kwb
+
+kwimage support available with mkimage utility will generate kirkwood boot
+image that can be flashed on the board NAND/SPI flash
+
+Board specific configuration file specifications:
+------------------------------------------------
+1. This file must present in the $(BOARDDIR) and the name should be
+	kwbimage.cfg (since this is used in Makefile)
+2. This file can have empty lines and lines starting with "#" as first
+	character to put comments
+3. This file can have configuration command lines as mentioned below,
+	any other information in this file is treated as invalid.
+
+Configuration command line syntax:
+---------------------------------
+1. Each command line is must have two strings, first one command or address
+	and second one data string
+2. Following are the valid command strings and associated data strings:-
+	Command string		data string
+	--------------		-----------
+	BOOT_FROM		nand/spi/sata
+	NAND_ECC_MODE		default/rs/hamming/disabled
+	NAND_PAGE_SIZE		any uint16_t hex value
+	SATA_PIO_MODE		any uint32_t hex value
+	DDR_INIT_DELAY		any uint32_t hex value
+	DATA			regaddr and regdara hex value
+	you can have maximum 55 such register programming commands
+
+3. All commands are optional to program
+
+Typical example of kwimage.cfg file:
+-----------------------------------
+
+# Boot Media configurations
+BOOT_FROM	nand
+NAND_ECC_MODE	default
+NAND_PAGE_SIZE	0x0800
+
+# Configure RGMII-0 interface pad voltage to 1.8V
