Awesome idea!

One comment: can you please check whether, if you replace

#include <Uefi.h>

with

#include <Uefi/UefiBaseType.h>

then stuff will still build?

Both SerialPortLib instances are BASE, so we should not include <Uefi.h>
(in particular <Uefi/UefiSpec.h> included by it).

If it works, then:

If it doesn't work, then I think we should figure out why not; it could
be a sign of some layering violation, which would be nice to document at
least in the commit message.

Thanks
Laszlo
