Bug Description
The current uc22 beta image (2022-04-11) shows nothing on the serial console during boot, nor does it allow console-conf over serial console.
I've double checked with jammy, focal, and uc20 and my serial console is working fine with all of those images on this same device (an rpi3b+) but with uc22 I don't see any output at all.
Kernel version:
Linux ubuntu 5.15.0-1005-raspi #5-Ubuntu SMP PREEMPT Mon Apr 4 12:25:49 UTC 2022 armv7l armv7l armv7l GNU/Linux
One thing I did notice, is that I do not see a ttyS0 device, which appears to be what it's expecting to use for the serial console
