Hi Yannic,

I haven't had time to dig into it in detail yet but it looks like
imx8m boards are failing again in master due to tee changes again and
perhaps its this series that is causing it.

Here's what I see with today's mater:
make imx8mm_evk_defconfig
make
...
  BINMAN  .binman_stamp
Image 'image' is missing optional external blobs but is still functional: tee-os

binman: module 'importlib.resources' has no attribute 'files'
make: *** [Makefile:1339: .binman_stamp] Error 1

I thought I had read something about a warning that wasn't an error
but above is clearly a build failure.

Am I missing something here?

Best Regards,

Tim
