What is the advantage of documenting unwired devices? I ask because the
taco does not have emac1 connected. I handle it by not defining emac1 in
the dts file.
Is it better to document it and disable it? Or is this mainly for
reference boards to show that while the PPC supports to emacs, only one
is enabled on the reference board?
i.e. We want reference design boards to show what *could* be done, but
production boards to show what *is* done?
Cheers,
Sean
