So since I do want to avoid adding user-selectable configs if
possible, here are some concrete thoughts on this patch, trying to
provide an example from my more abstract rants down thread. :)
I think we should be using the CONFIG_BUILD_TEST (or whatever
it's called) here to allow building the drivers everywhere but
at the same time be specific with the platform. How about this:
config EM_TIMER_STI
bool "Renesas EMMA EV2 STI timer driver" if BUILD_TEST && !ARCH_EMEV2
default ARCH_EMEV2
help
...
This makes it a silent option that is set correctly all the time
but lets you enable it everywhere when BUILD_TEST is set.
It sounds like a good compromise.
We could skip the "&& !ARCH_EMEV2" part to allow building an
EMEV2 kernel without this driver when build testing if that
is possible.
