Hello,
First patch is a fix that otherwise prevents using the serial on some
(newish?) Intel AMT devices (at least the one I have). Patches 2 and 3
are general improvements and cleanups. Finally patch 4 adds support for
getting the serial configuration from ACPI SPCR table.
Thanks, Roger.
Roger Pau Monne (4):
xen/uart: be more careful with changes to the PCI command register
xen/uart: switch ns16550 to use pci_sbdf_t
xen/uart: report an error if the device type is not supported
xen/uart: enable parsing ACPI SPCR on x86
