drivers/rpmsg: remove depends on CONFIG_EXPERIMENTAL The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

rpmsg: add virtio-based remote processor messaging bus Add a virtio-based inter-processor communication bus, which enables kernel drivers to communicate with entities, running on remote processors, over shared memory using a simple messaging protocol. Every pair of AMP processors share two vrings, which are used to send and receive the messages over shared memory. The header of every message sent on the rpmsg bus contains src and dst addresses, which make it possible to multiplex several rpmsg channels on the same vring. Every rpmsg channel is a device on this bus. When a channel is added, and an appropriate rpmsg driver is found and probed, it is also assigned a local rpmsg address, which is then bound to the driver's callback. When inbound messages carry the local address of a bound driver, its callback is invoked by the bus. This patch provides a kernel interface only; user space interfaces will be later exposed by kernel users of this rpmsg bus. Designed with Brian Swetland <swetland@google.com>.

rpmsg: Introduce Qualcomm SMD backend This introduces a new rpmsg backend for the Qualcomm SMD system, allowing communication with various remote processors found in Qualcomm platforms. The implementation is based on, and intends to replace, drivers/soc/qcom/smd.c with the necessary adaptions for fitting with the rpmsg core.

rpmsg: smd: fix dependency on QCOM_SMD=n The ARM allmodconfig build broke with the addition of the SMD rpmsg driver that conflicts with the driver its replaces: WARNING: drivers/soc/qcom/smd: 'qcom_smd_register_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.ko WARNING: drivers/soc/qcom/smd: 'qcom_smd_unregister_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.ko There is already a dependency that is meant to avoid the broken configuration, but that only prevents the case where at least one of the two are built-in, but not if both are modules. This changes the dependency to "=n", to ensure that the new driver can only be enabled if the other one is completely disabled.
