I just went to see why my CI boot of 44x didn't catch this, and it's
because I don't use the uImage, I just boot the vmlinux directly:

  $ qemu-system-ppc -M bamboo -m 128m -display none -kernel build~/vmlinux -append "console=ttyS0" -display none -nodefaults -serial mon:stdio
  Linux version 5.8.0-rc1-00118-g69119673bd50 (michael@alpine1-p1) (gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #4 Wed Jun 17 20:19:22 AEST 2020
  Using PowerPC 44x Platform machine description
  ioremap() called early from find_legacy_serial_ports+0x690/0x770. Use early_ioremap() instead
  printk: bootconsole [udbg0] enabled


So that's probably the simplest solution?

cheers
