Review Comment:
> > the semantics of nuttx (and many of unix-like systems) is "always
O_BINARY". it seems a bit awkward to distinguish binary/text only for hostfs.
isn't it simpler to always use O_BINARY in hostfs for windows?

un/translated, I think bring back the O_BINARY define is a simply resolution
for this case...
what apps are they using?
usually apps for nuttx (or unix in general) doesn't specify their
text/binary intention.
iirc posix even states fopen "b" mode is no-op.
i guess an alternative is to have a mount flag of hostfs.
