Not sure which specific early console you are referring to.
Currently we have serial, ttyS, vga, dbgp, xen, efi and pciserial in
arch/x86/kernel/early_printk.c, and only pciserial is memory mapped
(but it's being removed).

And this patch only touches pciserial/serial parts so ideally shouldn't
have impact on other early consoles.
