I re-tested this patch series and found that it build (as I would have
expected) without errors when using the "make" commands:

$ make mrproper
$ make db-88f6820-gp_defconfig 
#
# configuration written to .config
#
$ make -j10 -s
$ ll u-boot.kwb 
-rw-rw-r-- 1 stefan stefan 175708 Mai  4 09:47 u-boot.kwb
$ make 

Only when run via buildman this error shows:

$ ./tools/buildman/buildman db-88f6820-gp
boards.cfg is up to date. Nothing to do.
Building current source for 1 boards (1 thread, 8 jobs per thread)
       arm:  +   db-88f6820-gp     
+Didn't find the file 'board/Marvell/db-88f6820-gp/binary.0' in '/home/stefan/git/u-boot/.bm-work/00/build' which is mandatory to generate the image

+make: *** [sub-make] Error 2
    0    0    1 /1      db-88f6820-gp

Do you have an explanation why this is the case? The file
board/Marvell/db-88f6820-gp/binary.0 is available and building
via "make" does work. Where does this difference come from?

Thanks,
Stefan
