Thanks for this tiny but important fix on your patchset. In fact, I was able to verify that now with your latest v5 patchset for the initial rpi5 support even newer/latest rpi-eeprom versions work as expected and u-boot is chain loaded by the rpi boot loader.

So thanks again for that fix and I am looking forward to seeing your patchset integrated and hopefully also maintained in future so that USB boot and GPIO support will be added in the near future.
