Juno has several serial ports, one of which may be used for a remote debug interface (e.g. gdb, WinDbg). The debug serial port needs to be distinct from that used for UEFI trace to prevent corruption of debugger protocol messaging. The UEFI spec requires that serial devices be initialised to default settings. (11.8 Serial I/O Protocol - "The default attributes for all UART-style serial device interfaces are: 115,200 baud, ..." and 17.3.3 EFI Debugport Variable - "These defaults must be used in the absence of a DEBUGPORT variable...") This change adds initialization of the serial device reported in the ACPI DBG2 table. The initialisation is done early in the boot to allow the possibility of remote debug of UEFI itself. NOTE: This is functionally dependent on the DBG2 table being updated in OpenPlatformPkg, but is required as a precursor to that change.
