The default kernel cmdline does not enable the tty console correctly on my system. I see only a black screen on all ports and graphics adpaters (built-in ASpeed + PCIe Radeon GPU) connected to the system. If I manually change the kernel cmdline and add "console=tty1" I can see the boot messages (after a quite long wait time) and the shell on the ASpeed VGA. Reproducible: Always Steps to Reproduce: 1. Insert Gentoo install-ppc64(le)-minimal installation CD/USB 2. Boot system 3. Select default menu entry Actual Results: I only see a black screen (sometimes with a blinking cursor) on the display connected to the built-in ASpeed graphics. The dedicated PCIe GPU does not produce any output. Expected Results: See the boot messages and shell on the ASpeed VGA. In my opinion it would be great if there were multiple boot menu entries for different consoles. While desktop users likely prefer VGA, people installing a server may prefer to use the serial console (even if the server has a VGA port).
Adding console=tty1 to the bootargs works in qemu-system-ppc65 as well, however I'd like some more opinions before adding this fix as a PR.
