CPExxx and WBSxxx boards with AR9344 SOC use the OKLI lzma kernel loader with the offset of 3 blocks of length 4k (0x3000) in order to have a fake "kernel" that cannot grow larger than how it is defined in the now static OEM partition table. Before recent changes to the mtdsplit driver, the uImage parser for OKLI only supported images that started exactly on an eraseblock boundary. The mtdsplit parser for uImage now supports identifying images with any magic number value and at any offset from the eraseblock boundary using DTS properties to define those values. So, it is no longer necessary to use fixed sizes for kernel and rootfs Tested-by: Andrew Cameron <apcameron@softhome.net> [CPE510 v2] Tested-by: Bernhard Geier <freifunk@geierb.de> [WBS210 v2] Tested-by: Petrov <d7c48mWsPKx67w2@gmail.com> [CPE210 v1] Signed-off-by: Michael Pratt <mcpratt@pm.me>
