Short version: (a.k.a caveman version)
- Compile-time option: bad.
- Run-time option: good.
Long version:
Without looking at the docs, I would hope that the some revision reg
or similar would report whether this feature is available or not. The
user configuring the kernel should not have to know whether his SoC
has this feature or not.
Kevin
