Hmm, I think I was bitten by this before... In my case setting a
CONFIG_DEVMEM=y in any of the targets-config like this did not what
its supposed to do.

This was because this setting gets "forced" by the CONFIG KERNEL_DEVMEM in our
own config/Config-kernel.in. So we might as well remove the CONFIG_DEVMEM
from all subtarget configuration. (I think the target/generic/config-X can
stay or there will be edit-wars).

(My best guess how these settings end up in the targets config, is that these
settings get there by accident when the configurations are refreshed upon a
kernel-bump.)

Cheers,
