This patch adds support for "kwbimage" (Kirkwood Boot Image)
image types to the mkimage code.

For details refer to docs/README.kwbimage

This patch is tested with Sheevaplug board

+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
