What is the point in making that work on x86 additionally to serial
support in early_printk? It might make sense to split away the serial
bits from early_printk.c and move them out of arch/ into -- say --
drivers/serial/, so other architectures can use that too and we have
only one serial earlyprintk implementation in the kernel. Not sure it
is worth the effort given the code size.
yes, we can drop serial bits from early_printk.c, and use
drivers/serial/8250_early.c and
with "earlycon=uart,io,0x3f8,9600n8", "early=ueart,mmio,0xfe000000,9600n8"
and we can extend other non 8250 compatitable uart to some *_early.c
in the same dir.
So other platform and other uart could be happy to get early console.
