Another update, I did this in adb shell:
echo PDA > /sys/devices/platform/switch-sio/uart_sel
Then rebooted the phone with my UART cable attached and now I get this:
Uncompressing Linux... done, booting the kernel.
So it's giving me output up until the kernel boots which told me the console attribute in the cmdline isn't set. I looked and that confirmed it that it wasn't. I will get the sourcecode for a kernel and compile it with the console attribute.
So yes, this phone will do UART. I just have to do it a bit weirdly.
