I'm sorry, I don't understand the point you're making.

Andrew's proposal was that we could add early_uart_ioremap to the list of
bt_ioremap and dmi_ioremap.

for i386, bt_ioremap is using fixmap, and it is temporary boot-time
mappings, used before ioremap() is functional.
but we need one as permanent fixed address.

for x86_64, early_ioremap. I'd like to make to static, because
dmi_ioremap could use ioremap instead.

Fix address could make the earlycon can be used more earlier.
