[PATCH v2 00/24] mtd: rawnand: Improve compile-test coverage

[boris.brezillon@xxxxxxxxxxx (Boris Brezillon)]

Hello,

This is an attempt at adding "depends || COMPILE_TEST" to all NAND
drivers that have no compile-time dependencies on arch
features/headers.

This will hopefully help us (NAND/MTD maintainers) in detecting build
issues earlier. Unfortunately we still have a few drivers that can't
easily be modified to be arch independent.

I tried to put all patches that only touch the NAND subsystem first,
so that they can be applied even if other patches are being discussed.

Don't hesitate to point any missing dependencies when compiled with
COMPILE_TEST. I didn't have any problem when compiling, but that might
be because the dependencies were already selected.

In this v2, I tried to fix all warnings/errors reported by kbuild/0day
robots. The only remaining ones are those in omap_elm.c which seems to
do some weird cpu_to_be32() conversions. I guess I could replace those
by iowrite32be() calls (or just add (__force __u32)), but I don't want
to risk a regression on this driver, so I'm just leaving it for someone
else to fix :P.

Regards,

Boris

Changes in v2:
- Fix a few problems reported by kbuild robots and Stephen Rothwell
