||||||
|
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 |
||||||
|
|
||||||
|
