How about console=uart8250,...?
I don't want to add asm-ia64/fixmap.h with dummy definitions
just for this.
Can we add this:
asm-ia64/io.h: #define bt_ioremap ioremap
asm-x86_64/io.h: #define bt_ioremap early_ioremap
and use bt_ioremap instead?
I will try it.

If you can make "console=early8250" work, we don't need
"earlycon=early8250", do we?
actually I modify init/main.c
diff --git a/init/main.c b/init/main.c
index 1940fa7..07dad53 100644

so make earlycon early_param setup will check console command line.
Your patch adds trailing whitespace and a few cases of"<space><tab>".
I use this in my .vimrc to catch these:
highlight WhitespaceEOL ctermbg=red guibg=red
match WhitespaceEOL /\s\+$\| \+\ze\t/
I will check it.
