Use ACPI SPCR on x86

2019-05-23T19:55:53+00:00

This takes the SPCR code currently in uart_cpu_arm64.c, moves it into
a new uart_cpu_acpi.c (with some associated refactoring), and uses it
from both arm64 and x86.

An SPCR serial port address AccessWidth field value of 0 ("reserved")
is now treated as 1 ("byte access") in order to work around a buggy
SPCR table on Amazon EC2 i3.metal instances.

add snps IP uart support / genaralize UART

2018-08-19T21:10:21+00:00

This is an amalgam of a patch by Doug Ambrisko to
generalize uart_acpi_find_device, imp moving the
ACPI table to uart_dev_ns8250.c and advice by jhb
to work around a bug in the EPYC 3151 BIOS
(the BIOS incorrectly marks the serial ports as
disabled)
