Currently, RPMSG_VIRTIO can only be enabled if some other kconfig
option selects it. This does not allow it to be enabled for
virtualized systems where Virtio RPMSG is available over Virtio
MMIO or PCI transport.
This patch updates RPMSG_VIRTIO kconfig option so that we can
enable the VirtIO RPMSG driver via menuconfig or defconfig. The
patch also removes "select RPMSG_VIRTIO" from various remoteproc
kconfig options because it is now user selectable.

When RPMSG_QCOM_GLINK_SMEM=m and one driver causes the qcom_common.c file
to be compiled as built-in, we get a link error:

Out of the three PIL driver instances, QCOM_ADSP_PIL already has a
Kconfig dependency to prevent this from happening, but the other two
do not. This adds the same dependency there.

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.

The Texas Instrument's Keystone 2 family of SoCs has 1 or more
TMS320C66x DSP Core Subsystems (C66x CorePacs). Each subsystem has
a C66x Fixed/Floating-Point DSP Core, with 32KB of L1P and L1D SRAMs,
that can be configured and partitioned as either RAM and/or Cache,
and 1 MB of L2 SRAM. The CorePac also includes an Internal DMA (IDMA),
External Memory Controller (EMC), Extended Memory Controller (XMC)
with a Memory Protection and Address Extension (MPAX) unit, a Bandwidth
Management (BWM) unit, an Interrupt Controller (INTC) and a Powerdown
Controller (PDC).
A new remoteproc module is added to perform the device management of
these DSP devices. The driver expects the firmware names to be of the
form "keystone-dsp<X>-fw", where X is the corresponding DSP number, and
uses the standard remoteproc core ELF loader. The support is limited
to images only using the DSP internal memories at the moment. This
remoteproc driver is also designed to work with virtio, and uses the
IPC Generation registers for performing the virtio signalling and
getting notified of exceptions.
The driver currently supports the 66AK2H/66AK2K, 66AK2L and 66AK2E
SoCs.

The davinci remoteproc driver requires a CMA pool for allocating
memory for virtio vrings/buffers and other sections of the firmware
image. The allocations are done using the DMA API. The CMA option is
currently selected automatically on systems with MMU when davinci
remoteproc is enabled, switch this to a saner depends on dependency
convention. The dependency is also updated to use the DMA_CMA kconfig
symbol that is used for CMA allocations using the DMA API, the CMA
dependency is inherited implicitly.

Back in July 2014 I asked around what was the intended target
platform for the STE Modem remoteproc driver, so that I could add the
proper hardware dependency to its config option. The answer I got was
that there was no known publicly available hardware needing it and it
was unlikely that there ever would.
So I think it's time to delete this driver to lower the maintenance
burden.

The tie between the main WCNSS driver and the IRIS driver causes a
circular dependency between the two modules. Neither part makes sense to
have on their own so lets merge them into one module.
For the sake of picking up the clock and regulator resources described
in the iris of_node we need an associated struct device. But, to keep
the size of the patch down we continue to represent the IRIS part as its
own platform_driver, within the same module, rather than setting up a
dummy device.

Make REMOTEPROC core a selectable kconfig option, and update
remoteproc client drivers to 'depends on' the core. This avoids
some nasty Kconfig recursive dependency issues. Also when using
menuconfig client drivers will be hidden until the core has been
enabled.
Documentation/kbuild/kconfig-language.txt:
Note:
select should be used with care. select will force
a symbol to a value without visiting the dependencies.
By abusing select you are able to select a symbol FOO even
if FOO depends on BAR that is not set.
In general use select only for non-visible symbols
(no prompts anywhere) and for symbols with no dependencies.
That will limit the usefulness but on the other hand avoid
the illegal configurations all over.

slim core is used as a basis for many IPs in the STi
chipsets such as fdma and demux. To avoid duplicating
the elf loading code in each device driver a slim
rproc driver has been created.
This driver is designed to be used by other device drivers
such as fdma, or demux whose IP is based around a slim core.
The device driver can call slim_rproc_alloc() to allocate
a slim rproc and slim_rproc_put() when finished.
This driver takes care of ioremapping the slim
registers (dmem, imem, slimcore, peripherals), whose offsets
and sizes can change between IP's. It also obtains and enables
any clocks used by the device. This approach avoids having
a double mapping of the registers as slim_rproc does not register
its own platform device. It also maps well to device tree
abstraction as it allows us to have one dt node for the whole
device.
All of the generic rproc elf loading code can be reused, and
we provide start() stop() hooks to start and stop the slim
core once the firmware has been loaded. This has been tested
successfully with fdma driver.

Add a remoteproc driver to load the firmware and boot a small
Wakeup M3 processor present on TI AM33xx and AM43xx SoCs. This
Wakeup M3 remote processor is an integrated Cortex M3 that allows
the SoC to enter the lowest possible power state by taking control
from the MPU after it has gone into its own low power state and
shutting off any additional peripherals.
The Wakeup M3 processor has two internal memory regions - 16 kB of
unified instruction memory called UMEM used to store executable
code, and 8 kB of data memory called DMEM used for all data sections.
The Wakeup M3 processor executes its code entirely from within the
UMEM and uses the DMEM for any data. It does not use any external
memory or any other external resources. The device address view has
the UMEM at address 0x0 and DMEM at address 0x80000, and these are
computed automatically within the driver based on relative address
calculation from the corresponding device tree IOMEM resources.
These device addresses are used to aid the core remoteproc ELF
loader code to properly translate and load the firmware segments
through the .rproc_da_to_va ops.

The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.
The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).
As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
and private header files. The public header has only the API related
functions and types.
- The module name mailbox.ko from plat-omap is changed to
omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
mailbox_omap1.ko for OMAP1
mailbox_omap2.ko for OMAP2+

Patch a62a6e98 "ARM: OMAP2+: Disable code that currently does not work
with multiplaform" makes the OMAP_MBOX_FWK option depend on !MULTIPLATFORM,
which means we cannot simply select that symbol from OMAP_REMOTEPROC.
Turning the 'select' into 'depends on' ensures that all dependencies
are correct until OMAP_MBOX_FWK loses its dependency.
Without this patch, building allmodconfig results in:

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.

Add support for the STE modem shared memory driver.
This driver hooks into the remoteproc framework
in order to manage configuration and the virtio
devices.
This driver adds custom firmware handlers, because
STE modem uses a custom firmware layout.

Remoteproc requires user space firmware loading support, so
let's select FW_LOADER explicitly to avoid painful misconfigurations
(which only show up in runtime).

OMAP_REMOTEPROC selects REMOTEPROC and RPMSG, both of which depend
on EXPERIMENTAL, so let's have OMAP_REMOTEPROC depend on EXPERIMENTAL
too, in order to avoid the below randconfig warnings.
warning: (OMAP_REMOTEPROC) selects REMOTEPROC which has unmet direct dependencies (EXPERIMENTAL)
warning: (OMAP_REMOTEPROC) selects RPMSG which has unmet direct dependencies (EXPERIMENTAL)
