really sorry for that, I should have seen it before. Shouldn't we also
make the U-Boot partition greater when we move the start of kernel
partition?
Can you please send another version, rest is fine (checkpatch, apply
cleanly, no build errors).

also sorry, but size is wrong here! We reduced the partition to
0x1CE000, it is about 1.8 MiB now and not 2 MiB as before.
