Hello Simon! I have already pushed these patches to github due to CI testing. So you can easily access them via git fetch/checkout. Before (this is already in u-boot git): $ git checkout a298d4fbcdba1b38e48ea2af0fc5386cab2070da After1: $ git fetch https://github.com/u-boot/u-boot.git refs/pull/83/head $ git checkout 1f038c8b45ef0018e52a2a4587eb73170769ac2f After2: = use After1 with: + disable CONFIG_SYS_THUMB_BUILD + enable CONFIG_OF_LIBFDT_OVERLAY + enable CONFIG_CMD_FDT defconfig file is nokia_rx51_defconfig
