And arm64?

Any chance we can rename param to "spcr" or something more clear?
To explicitly state what exactly it's going to do. `auto' sounds
too general and doesn't tell me that much. I'm probably the only
here who can't see a connection between "auto" and "SPCR", but

One more thing, as far as I can tell, acpi_parse_spcr() can fail
and return an error. arch_console_setup() hides all errors and
returns void. Should it return error code?

int arch_console_setup(void)
return acpi_parse_spcr(false, true);

Or maybe

void arch_console_setup(void)
if (acpi_parse_spcr(false, true))

There can be other consoles in the system, logging an error is not
such a useless thing.
