[PATCH 0/4] Some remoteproc/rpmsg Kconfig cleanups

[Suman Anna]

Hi Bjorn,

The following are some Kconfig related cleanups on rpmsg and remoteproc
to help resolve the current build related warnings reported on linux-next
after the rpmsg for-next merges. 

The first 2 patches drop the VIRTUALIZATION dependency (there is never
a true dependency) that were introduced a long while back to fix a
dependency issue on VIRTIO, and is no longer needed. This cleanup
results in the elimination of the ppc64_defconfig warnings against
the davinci remoteproc driver (davinci is ARMv5, and should have no
dependency against PPC arch whatsoever, that warning can be seen
without the keystone remoteproc patches).

The third patch is a pure cleanup patch, and the last patch is an
alternate fix for the linux-next Kconfig warnings, without your patch
to change the RPMSG_VIRTIO dependency [1]. Last patch can also go with
your patch, but feel free to drop it if picking up your patch instead.

Patches are based directly on linux-next 20170627 tag, They also apply
fine on mainline 4.12-rcs.

regards
Suman

[PATCH 1/4] rpmsg: Drop VIRTUALIZATION dependency from RPMSG_VIRTIO

[Suman Anna]

A dependency to VIRTUALIZATION has been added to RPMSG_VIRTIO (back
when it was named RPMSG) in v3.10 kernel in commit 397944df3290
("rpmsg: fix kconfig dependencies for VIRTIO") to resolve Kconfig
warnings due to the inclusion of the virtio configuration file from
the ARM's KVM config file. The KVM config was fixed properly in the
subsequent release in commit 8bd4ffd6b3a9 ("ARM: kvm: don't include
drivers/virtio/Kconfig"). So, drop this unneeded VIRTUALIZATION
dependency from RPMSG_VIRTIO.

[PATCH 2/4] remoteproc: Drop VIRTUALIZATION dependency from REMOTEPROC

[Suman Anna]

A dependency to VIRTUALIZATION has been added to REMOTEPROC in v3.10
kernel in commit b9777859ec01 ("remoteproc: fix kconfig dependencies
for VIRTIO") to resolve Kconfig warnings due to the inclusion of the
virtio configuration file from the ARM's KVM config file. The KVM
config was fixed properly in the subsequent release in commit
8bd4ffd6b3a9 ("ARM: kvm: don't include drivers/virtio/Kconfig").
So, drop this unneeded VIRTUALIZATION dependency from REMOTEPROC.

[PATCH 3/4] remoteproc: Drop redundant REMOTEPROC dependency from driver Kconfigs

[Suman Anna]

All the remoteproc platform driver Kconfig symbols are defined and
included under an if REMOTEPROC condition, so the dependency on
REMOTEPROC is implicit and they do not need an explicit 'depends
on REMOTEPROC' line. So, clean these up.

[PATCH 4/4] remoteproc/keystone: Fix circular dependencies for ARM configs

[Suman Anna]

Drop the dependency on RESET_CONTROLLER for the Keystone remoteproc
driver to resolve some circular dependencies around different choices
for RESET_CONTROLLER on common ARM configs. This dependency is
inherent as the RESET_CONTROLLER will be enabled due to the enabled
ARCH_HAS_RESET_CONTROLLER for ARCH_KEYSTONE.

As my approach requires synchronized changes to rproc-next and
rpmsg-next and we're close to the merge window I'll pick this
"workaround" for now, thanks!

I do think it's appropriate for the Keystone remoteproc driver to
express its dependency on reset-controller, so I intend to revert this
as I look into this issue after -rc1 again.


Merged all 4 patches.

Bjorn
