 It means that a BIOS IO port for a UART won't work for EFI.  No value
 for DEBUG_PORT will do anything unless someone's got some translation
 "glue" to take the attempts to open the UART and use an EFI handle
 instead.

Weird as it sounds I was able to send debug info to COM2
(redirected to a pipe) on EFI64 VMware workstation clients.
I got the debug messages on a terminal emulator pointing 
to the pipe. It does work.
