> SERIAL_CORE_CONSOLE
>
> When EARLY_PRINTK is enabled and TTY is disabled, Kbuild gives the
> following warning:
>
> WARNING: unmet direct dependencies detected for
> SERIAL_CORE_CONSOLE
> Depends on [n]: TTY [=n] && HAS_IOMEM [=y]
> Selected by [y]:
> - EARLY_PRINTK [=y]
>
> This is because EARLY_PRINTK selects SERIAL_CORE_CONSOLE without
> selecting or depending on TTY, despite SERIAL_CORE_CONSOLE depending
> on TTY.
