The main board is UART0, while the serial output on the UART board is UART3. All serial outputs (arm-tf, op-tee, uefi and kernel) used to be on UART0. Later arm-tf (except bl1), uefi and kernel moved to UART3, so you should see [2] on UART0 and then booting (log directly above) should continue on UART3, assuming you're using a recent enough image.
aaaaah! I wasn't expecting partial output on UART0, then on UART3.
After setting the right jumper settings on the UART board, I'm now seeing the BL1 on UART0 and the rest on UART3 (a.k.a. UART1 on the UART board... which is also confusing.)
Thanks for the explanation and the help.
Next step, built a mainline u-boot that's using the UART board...
