I was about to apply this... but it doesn't build. It fails to build
during the U-Boot build process:

  CC      net/arp.o
  LD      test/dm/built-in.o
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named libfdt

  CC      lib/efi_loader/efi_disk.o
*** binman needs the Python libfdt library.
*** Either install it on your system, or try:
***
*** sudo apt-get install swig libpython-dev
***
*** to have U-Boot build its own version.
Makefile:1359: recipe for target 'checkbinman' failed
make[2]: *** [checkbinman] Error 1
make[2]: *** Waiting for unfinished jobs....

This is a build issue not really specific to this defconfig: any
defconfig using the binman too will fail this way. I guess we need to
package the Python libfdt library for the host, and provide a U-Boot
sub-option that allows the user to say "my defconfig needs the Python
libfdt library".

A few other comments below.

Please refresh on the latest master, where I've changed to use your full nemae.

Please drop the post-build.sh script, it is not needed: use
BR2_TARGET_UBOOT_BOOT_SCRIPT instead.

As said above: use BR2_TARGET_UBOOT_BOOT_SCRIPT.

You can drop.

Drop the last argument here.

And drop this last line.

Could you fix these issues, especially the build issue, and send an
updated version?

Thanks!
