MACH_REALTEK_RTL declares that the system supports early printk , but
this is not actually implemented as intended. The system is left with a
non-functional early0 console because the setup_8250_early_printk_port()
call provided for MIPS_GENERIC is never used to set this up. Generic
ns16550a earlycon works, so devices should use that for early output.
This means that SYS_HAS_EARLY_PRINTK and USE_GENERIC_EARLY_PRINTK_8250
do not need to be selected.

Additionally, as reported by Lukas Bulwahn, the selected symbol
SYS_HAS_EARLY_PRINTK_8250 does not actually exist, so should also be
dropped.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
