Parse and use the keep parameter of earlyprintk to avoid having the kernel output stop with:
Console: colour dummy device 80x30 console [tty0] enabled bootconsole [earlycon0] disabled This happens because once tty0, the virtual terminal console is registered, it is selected as the default console, disregarding an existing stdout-path DT property and the early console is shutdown before the console driver is probed.
