The above changes are for shmobile SoC defconfigs which I maintain
(as is one other patch in the series).
While the below ones are not.

With regards to updating shmobile configuration options,
we have recently moved towards using Kconfig rather than
defconfig in cases where selecting A means we really ought
to select B too. Something along the lines of:

	select CONFIG_MTD_SPI_NOR if CONFIG_MTD_M25P80

Do you consider that CONFIG_MTD_SPI_NOR should always
be selected if CONFIG_MTD_M25P80 if selected?

If so, perhaps it would be best to update the CONFIG_MTD_M25P80 Kconfig
node to select CONFIG_MTD_M25P80. This would probably imply that most
if not all of this series would no longer be needed.

If not, would you be able to make a patch to add something like
the above snippet to arch/arm/shmobile/Kconfig (probably more than once)
and drop the changes to shmobile defconfigs from this series?

The above change seems unrelated to the subject of the patch.

If its valid then I'd prefer it submitted as a separate patch.
