From 5031fbfd22c9a2c126bcab92998d70342b044c5e Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Tue, 25 Feb 2020 20:07:39 +0100 Subject: [PATCH] layerscape: ls1012afrdm: introduce dynamic partitioning Combine fixed sizes of "kernel" and "rootfs" partitions into one partition managed by OpenWrt splitter, it will allow better management of chip capacity and less maintenance burden when compiled kernel image will outgrow allocated size for kernel partition. This also changes kernel image format, since splitter only manages kernel and rootfs partitions, the dtb needs to be updated with the kernel, so for convenience, kernel is packed to FIT image.
