I like the idea very much, but am not sure about the implementation. This problem has been around for a while (just search the archives for people wondering how to deal with a switch chip connected via rvMII or whatever). The trickiest part of this is how to get the information to the driver. I've always thought that the best way would be for board code to initialize each controller through proper C code (i.e. not CONFIG macros). But there's definitely something to be said for doing it all through macros, since that's how Kconfig works. Please have a look at the code that Andy Fleming recently submitted for the TSEC driver (it's in the main branch now). He passes a tsec_info_struct into each call of tsec_initialize(), allowing all type of custom information to go in. In my mind, that could be generalized to something that more than just TSEC, but let's take baby steps.
Yes, this looks like a good approach. Not sure if we should go all the way or accept Victors approach for now. Moving to this parameter based initialization is a different matter that should really be done soon.
Incidentally, the term "Fixed PHY" has already been coined for what you're calling "PHY-less". I suggest we standardize.
Yes. Is there already a define available?
Anyway, I have to go to bed. Eyes are starting to close and brain's sloowwwiing doowwn.
Heh :)
