FWIW... I just used my updated u-boot script to update the image for 186 and went through the setup process using serial console for my Raspberry Pi. My process:
* Download backup from IPFire * Flash new image to SD Card * Update u-boot script * Make new image using script * Boot and do initial setup via serial console * Login to web admin and restore backup
Even though this is a few more steps than just doing an "in place" upgrade, I actually like that I am keeping the previous SD card and can swap back if something goes wrong.

Thanks. That was my original conversation! :-) I will just wait for Arne to find some time.

Hello Craig,
Hmm, I am not the right person to talk to about this, but it looks this has all been discussed here already:

Thanks Michael,
Is there anything more you need me to do? I assume most of the current effort is currently focused on the test release.
Thanks, Craig

Hello Craig,
Thank you very much for this patch. This is perfectly readable :)
It looks logical to me, however I am not an expert when it comes to SBCs, so I will leave this for Arne to review and merge.
Best, -Michael

Updates to u-boot script for Raspberry Pi 4b devices to properly configure the serial console and to choose the proper boot address to be used on newer board revisions. With these changes in place, I'm able to fully boot into a serial console in u-boot.
The serial console configuration was derived from the Grub configuration, while the boot address changes were taken from the IPFire Raspberry 4b documentation page: https://www.ipfire.org/docs/hardware/arm/rpi/four
Per the conversation in the forums, I don't know why the boot address changes are required. I was simply trying to automate those changes such that downloaded builds will work out of the box. https://community.ipfire.org/t/hang-with-kernel-starting-on-raspberry-pi/115...
NOTE: The use of the different parameter options to the test command to minimize the need for deeply nested conditionals. I did try more bash-shell like syntax, but u-boot didn't seem to like that. The operators used here were found in the u-boot source.
