+---------------------------------------------
+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
+
+Commad syntax:
+./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 data strings associated
combinations
+ Command string data string
+ BOOT_FROM nand/spi/sata
+ NAND_ECC_MODE default/rs/hamming/disabled
+ NAND_PAGE_SIZE any u16 hex value
+ SATA_PIO_MODE any u32 hex value
+ DDR_INIT_DELAY any u32 hex value
+ <u32 register address> <u32 vlaue for it>, you can have maximum 55
such 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
+0xFFD100e0 0x1b1b1b9b
+# DRAM Configuration
+0xFFD01400 0x43000c30
+0xFFD01404 0x37543000
+0xFFD01408 0x22125451
