[PATCH 4/5] serial: convert early_uart to earlycon for 8250

+config FIX_EARLYCON_MEM
+ bool
+ depends on X86
+ default y

It might have been nicer to do this in arch/i386/Kconfig and
arch/x86_64/Kconfig. That way we don't end up with a great string of arch
selectors in non-arch Kconfig files (do "grep SPARC */Kconfig*")

otoh, doing that means that FIX_EARLYCON_MEM doesn't get mentioned in
drivers/serial/Kconfig and you need to go on a great hunting expedition to
find out who sets it.


we could extend that to others arch that is support fixmap like
./asm-i386/fixmap.h
./asm-mips/fixmap.h
./asm-parisc/fixmap.h
./asm-sh/fixmap.h
./asm-sparc/fixmap.h
./asm-um/fixmap.h
./asm-x86_64/fixmap.h

so it will be
>> +config FIX_EARLYCON_MEM

You you can provide another config like

CONFIG_FIXMAP
