Support splitting WRG images, which can be found in older D-Link devices. Signed-off-by: George Hopkins <george-hopkins@null.net>
The D-Link devices with JBOOT bootloader use their own kernel image header (stag + sch2 headers). This driver find jImage header and set rootfs start after kernel file. Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com>
The splitter ignored the rootfs offset from the header, probably because until c1e6e61 it was invalid. This patch fixes the splitter to use the now correct header data. Regarding target/linux/ar71xx/files/drivers/mtd/tplinkpart.c, this particular splitter "falls back" to the correct rootfs offset reading and as such it doesn't need to be updated, although it will report a kernel partition length that can be larger than the actual length as it assumes that partition fills the entire segment up to the rootfs partition.

The RouterBOOT bootloader does not care where the kernel lives in the SPI flash, all that matters is that the kernel is wrapped in the custom yaffs container as generated by kernel2minor. This container has a fixed signature as follows: 00000000 00 00 00 01 00 00 00 01 ff ff 6b 65 72 6e 65 6c |..........kernel| This patch adds mtdsplit support for identifying that signature and triggering the search for the rootfs. rootfs is expected at EB boundary since we use wget mtd_find_rootfs_from(). We make no use of the yaffs file size field because it contains invalid data in the image generated by kernel2minor. Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>

This patch adds supports for the WNR2000v1 board with 4MB flash, and produces device-specific factory, rootfs, and sysupgrade files for the WNR2000v1. This board is errorneously claimed as supported on the OpenWRT wiki as AP81, but AP81 image would not work because of APT81 image requiring having 8MB of flash, while WNR2000v1 has only 4MB. The image requires the u-boot bootloader to be modified to fuhry's bootloader first. Short specification: - CPU: Atheros AR9132 - 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps - 4 MB of Flash - 32 MB of RAM - UART header (J1) on board - 1x button Factory/Initial flash instructions: - Set up a TFTP server on your local machine. - Download the uImage for ar71xx-generic and the rootfs image for ar71xx-generic-wnr2000 and save in the tftp server root. - Gain serial access to the router via the UART port (telnetenable over the network only won't work!). - Upgrade the u-boot bootloader to fuhry's version by running the script: http://fuhry.com/b/wnr2000/install-repart.sh - When the router restarts, interrupt u-boot and gain access to u-boot command line. - Repartititon the board and flash initial uImage and rootfs as follow. Commands to type in u-boot: # tells u-boot that we have a tftp server on 192.168.1.10 setenv serverip 192.168.1.10 # tells u-boot that the router should take the address 192.168.1.1 setenv ipaddr 192.168.1.1 # erase the region from 0x050000-0x3f0000 erase 0xbf050000 +0x3A0000 # loads sqfs.bin on TFTP server, and put it to memory address 0x81000000 tftpboot 0x81000000 sqfs.bin # it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ # copy bit by bit 0xZZZZZZ bytes from offset 0x050000 cp.b 0x81000000 0xbf050000 0xZZZZZZ # same to the uImage.bin, write it right next to sqfs.bin # again, 0xYYYYYY is the length that tftpboot reports tftpboot 0x81000000 uImage.bin cp.b 0x81000000 0xbf2a0000 0xYYYYYY # We need to tell the kernel what board it is booting into, and where to find the partitions setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd" # Tell u-boot where to find the uImage setenv bootcmd "bootm 0xbf2a0000" # Tell u-boot to save parameters to the u-boot-env partitions saveenv # Reset the board reset Tested on: - WNR2000v1 board. - Initial flash works. Known bugs: - I don't know why factory image doesn't work on initial flash on stock firmware in u-boot recovery mode while it should. - Sysupgrade does not yet work, if you do -f it will mess up your installation (requiring a reinstall of sqfs and uImage).

According to the author the code was added to in preparation for adding support for a new board. The patch for the board was never send and the code never really tested. The edimax header starting with the edimax magic is put in front of the uImage header. There is no special uImage header used. Means, default magic and the type field is set to kernel as usual.
