Benjamin Herrenschmidt	e37dbba665	term/serial: Avoid double lookup of serial ports ... The various functions to add a port used to return port->name, and the callers would immediately iterate all registered ports to "find" the one just created by comparing that return value with ... port->name. This is a waste of cycles and code. Instead, have those functions return "port" directly.

Benjamin Herrenschmidt	f5e1d23a18	term/ns8250: Support more MMIO access sizes ... It is common for PCI based UARTs to use larger than one byte access sizes. This adds support for this and uses the information present in SPCR accordingly.

Benjamin Herrenschmidt	7b192ec4cd	term/ns8250: Use ACPI SPCR table when available to configure serial ... "serial auto" is now equivalent to just "serial" and will use the SPCR to discover the port if present, otherwise defaults to "com0" as before. This allows to support MMIO ports specified by ACPI which is needed on AWS EC2 "metal" instances, and will enable GRUB to pickup the port configuration specified by ACPI in other cases.
