More serial ports in EFI bootstrap?

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

I have a Dell server with no serial port, and a serial console is highly
desirable for system administration. I wonder if EFI bootstrap could
be modified to use a serial port from a PCIe to serial card, or from a
USB to serial adapter.

Anyone has sone insights on the topic? Is it actually possible?
