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
