We have an analogous problem with large device tree kernels for ARM
(supporting a multitude of ARM subarchitectures): a lot of statically
compiled-in drivers that just idle around after boot.
What would be nice was for the kernel to have a way of marking some
platform drivers such that if it has not been probed by init_late(),
the entire driver would be discarded, like a module that gets unloaded.
When I posed this idea in some forum it was considered "pretty hard
to achieve" (plus I guess it runs into the dilemma that we can never
discard strings) but I still think it'd be the right thing to do. It'd be very
straight-forward for driver authors to annotate their on-chip platform
drivers with some MODULE_LATE_DISCARD() or whatever.
Yours,
