I've no idea what the right thing on Realview is because the documentation
is too poor in this area.  Although the Realview EB user manual gives you
the GPIO block signals, it doesn't say what sense they are.

It looks to me from the hardware description diagrams, that the GPIO block
is fed with an inverted signal from the socket card detect pin - which
itself is active low.  That means the GPIO signal is in a positive logic
state.

So I don't think that the "return !status;" is right even for the GPIO
case.
