I'm not sure about this (and below). We have two defines for the HSPOL,
high and low. If one of them is (x << y), shouldn't the other one be of
that style too?
It is inconsistent, but one macro describes bit set to 0 and the other
bit set to 1 (i.e. the actual bit) which is converted to BIT(n) macro. I
would be tempted to remove the bits set to 0, that's probably the real
discussion that should happen here. But that would also be a much bigger
patch. What do you think ?
