Your patchserie has 44 patches .. here buildman test 49 ...
It seems to me the first 3 patches and the last 2 are missing in
your series ...

Do you have a public git tree with this patches?
Ah, may:
http://git.denx.de/?p=u-boot/u-boot-dm.git;a=shortlog;h=refs/heads/kconfig-working3

Ok, I started tbot tc:
https://github.com/hsdenx/tbot/blob/master/src/tc/uboot/tc_uboot_check_kconfig.py
to check, if your series does not change u-boot.bin and spl/uboot-spl.bin

first outputs:
