Currently, Xen supports only DT based initialization of 16550 UART. This patch set adds support for initializing 16550 UART using ACPI SPCR table.
It also fixes one issue in HP Moonshot (HPE Proliant Aarch64) platform, which uses 16550 UART as a console. There is an erratum required to be implemented to make the UART console work.
