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>
