| 2 | Kirkwood Boot Image generation using mkimage | |
| 3 | --------------------------------------------- | |
| 4 | ||
| 5 | This document describes the U-Boot feature as it | |
| 6 | is implemented for the Kirkwood family of SoCs. | |
| 7 | ||
| 8 | The Kirkwood SoC's can boot directly from NAND FLASH, | |
| 9 | SPI FLASH, SATA etc. using its internal bootRom support. | |
| 10 | ||
| 11 | for more details refer section 24.2 of Kirkwood functional specifications. | |
| 12 | ref: www.marvell.com/products/embedded.../kirkwood/index.jsp | |
| 13 | ||
| 14 | Command syntax: | |
| 15 | -------------- | |
| 16 | ./tools/mkimage -l <kwboot_file> | |
| 17 | to list the kwb image file details | |
| 18 | ||
| 19 | ./tools/mkimage -n <board specific configuration file> \ | |
| 4946775c | 20 | -T kwbimage -a <start address> -e <execution address> \ |
| aa0c7a86 PW |
21 | -d <input_raw_binary> <output_kwboot_file> |
| 22 | ||
| 23 | for ex. | |
| 24 | ./tools/mkimage -n ./board/Marvell/openrd_base/kwbimage.cfg \ | |
| 4946775c | 25 | -T kwbimage -a 0x00600000 -e 0x00600000 \ |

| 32324b7f | 29 | kwbimage support available with mkimage utility will generate kirkwood boot |
| 1ff1f89c KP |
30 | image that can be flashed on the board NAND/SPI flash. The make target |
| 31 | which uses mkimage to produce such an image is "u-boot.kwb". For example: | |
| 32 | ||
| adbba996 | 33 | export KBUILD_OUTPUT=/tmp/build |
| 1ff1f89c KP |
34 | make distclean |
| 35 | make yourboard_config | |
| adbba996 | 36 | make u-boot.kwb |

| 39 | Board specific configuration file specifications: | |
| 40 | ------------------------------------------------ | |
| 1ff1f89c KP |
41 | 1. This file must present in the $(BOARDDIR). The default name is |
| 42 | kwbimage.cfg. The name can be set as part of the full path | |
| 93e14596 WD |
43 | to the file using CONFIG_SYS_KWD_CONFIG (probably in |
| 44 | include/configs/<yourboard>.h). The path should look like: | |
| 4ab3fc5e | 45 | $(CONFIG_BOARDDIR)/<yourkwbimagename>.cfg |
| aa0c7a86 PW |
46 | 2. This file can have empty lines and lines starting with "#" as first |
| 47 | character to put comments | |
| 48 | 3. This file can have configuration command lines as mentioned below, | |
| 49 | any other information in this file is treated as invalid. | |
| 50 | ||
| 51 | Configuration command line syntax: | |
| 52 | --------------------------------- | |
| 53 | 1. Each command line is must have two strings, first one command or address | |
| 54 | and second one data string | |
| 55 | 2. Following are the valid command strings and associated data strings:- | |
| 56 | Command string data string | |
| 57 | -------------- ----------- | |
| 58 | BOOT_FROM nand/spi/sata | |
| 59 | NAND_ECC_MODE default/rs/hamming/disabled | |
| 60 | NAND_PAGE_SIZE any uint16_t hex value | |
| 61 | SATA_PIO_MODE any uint32_t hex value | |
| 62 | DDR_INIT_DELAY any uint32_t hex value | |
| 63 | DATA regaddr and regdara hex value | |
| 64 | you can have maximum 55 such register programming commands | |
| 65 | ||
| 66 | 3. All commands are optional to program | |
| 67 | ||
| 68 | Typical example of kwimage.cfg file: | |
| 69 | ----------------------------------- | |
| 70 | ||
| 71 | # Boot Media configurations | |
| 72 | BOOT_FROM nand | |
| 73 | NAND_ECC_MODE default | |
