Hi Peng,

Thank you for the test, and apologies for not having validated the patch on
other targets.
In fact, this driver was not being used by any target (neither ARM nor PPC)
and after this patch it became enabled again. However, PPC targets fail
when trying to include the asm/ppc.h header, which is not available for
some reason.

For now, I am thinking of submitting a v3 of the patch adding an explicit
dependency on ARM, something like:

+ depends on ARM

This way we would avoid building the driver for PPC targets.
What do you think about this approach?

Thanks again for the report and the feedback.

BR,
Mateus
