I was able to get output by adding this to my kernel parameters:

console=ttyS0,115200 earlycon=uart8250,mmio32,0x1c020000

However, the console is flooded with messages like this:

[   42.982471] pcieport 0002:00:00.0:   TLP Header: 60001004 000000ff

I'm happy I can boot now. If I can also stop the errors, that'd be great.
