Public bug reported:

[Impact]
The serial console on HP Moonshot cartridges is connected to the chassis manager which currently expects data at 9600 baud. We are therefore hardcoding a kernel commandline argument of console=ttyS0,9600n8r. However, it is possible for this baud rate to change in the future. Using the firmware-controlled ${baudrate} setting instead of hardcoding the rate will allow us to adjust to such changes dynamically. Of course, it isn't a full solution (getty needs to be dynamic as well), but is required.
[Test Case]
Use test firmware from HP to bump the firmware from 9600 to 115200 and verify that the console output is still visible over the VSP (virtual serial port).
[Regression Risk]
It's easy to test that working combinations still work today.
