2 Kirkwood Boot Image generation using mkimage
3 ---------------------------------------------
5 This document describes the U-Boot feature as it
6 is implemented for the Kirkwood family of SoCs.
8 The Kirkwood SoC's can boot directly from NAND FLASH,
9 SPI FLASH, SATA etc. using its internal bootRom support.
11 for more details refer section 24.2 of Kirkwood functional specifications.
12 ref: www.marvell.com/products/embedded.../kirkwood/index.jsp
16 ./tools/mkimage -l <kwboot_file>
17 to list the kwb image file details
19 ./tools/mkimage -n <board specific configuration file> \
20 -T kwbimage -a <start address> -e <execution address> \
21 -d <input_raw_binary> <output_kwboot_file>
24 ./tools/mkimage -n ./board/Marvell/openrd_base/kwbimage.cfg \
25 -T kwbimage -a 0x00600000 -e 0x00600000 \
26 -d u-boot.bin u-boot.kwb
28 kwimage support available with mkimage utility will generate kirkwood boot
29 image that can be flashed on the board NAND/SPI flash
31 Board specific configuration file specifications:
32 ------------------------------------------------
33 1. This file must present in the $(BOARDDIR) and the name should be
34 kwbimage.cfg (since this is used in Makefile)
35 2. This file can have empty lines and lines starting with "#" as first
36 character to put comments
37 3. This file can have configuration command lines as mentioned below,
38 any other information in this file is treated as invalid.
40 Configuration command line syntax:
41 ---------------------------------
42 1. Each command line is must have two strings, first one command or address
43 and second one data string
44 2. Following are the valid command strings and associated data strings:-
45 Command string data string
46 -------------- -----------
47 BOOT_FROM nand/spi/sata
48 NAND_ECC_MODE default/rs/hamming/disabled
49 NAND_PAGE_SIZE any uint16_t hex value
50 SATA_PIO_MODE any uint32_t hex value
51 DDR_INIT_DELAY any uint32_t hex value
52 DATA regaddr and regdara hex value
53 you can have maximum 55 such register programming commands
55 3. All commands are optional to program
57 Typical example of kwimage.cfg file:
