Added initial support for SDM845 with ADSP bootup and shutdown operation
handled from Application Processor SubSystem(APSS).

Bjorn Andersson ef73c22fa0 remoteproc: qcom: Rename Hexagon v5 modem driver
The qcom_q6v5_pil implements support for the self-authenticating modem
subsystem. With the introduction of other q6v5 based non-TZ based
remoteproc driver the current name is cause for confusion, so rename it
to be more specific.

No functional change.

The Hexagon v5 ADSP driver is used for more than only the ADSP and
there's an upcoming non-PAS ADSP PIL for SDM845, so rename the driver to
qcom_q6v5_pas in order to better suite this.

Arnd Bergmann 12c2b509c0 remoteproc: qcom: fix Q6V5_WCSS dependencies
A new driver got added that depends on QCOM_SMD and fails to link
as built-in with CONFIG_QCOM_SMD=m:

drivers/remoteproc/qcom_common.o: In function `smd_subdev_stop':
qcom_common.c:(.text+0x674): undefined reference to `qcom_smd_unregister_edge'
drivers/remoteproc/qcom_common.o: In function `smd_subdev_start':
qcom_common.c:(.text+0x700): undefined reference to `qcom_smd_register_edge'

We've fixed the same thing several times before, so use the same
dependency here.

Geert Uytterhoeven 41a5985f17 remoteproc: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Sarangdhar Joshi 2666ca9197 remoteproc: Add remote processor coredump support
As the remoteproc framework restarts the remote processor after a fatal
event, it's useful to be able to acquire a coredump of the remote
processor's state, for post mortem debugging.

This patch introduces a mechanism for extracting the memory contents
after the remote has stopped and before the restart sequence has begun
in the recovery path. The remoteproc framework builds the core dump in
memory and use devcoredump to expose this to user space.

Anup Patel 4d91d7b099 rpmsg: Allow RPMSG_VIRTIO to be enabled via menuconfig or defconfig
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.

Suman Anna e88bb8f7a1 remoteproc/keystone: Add a remoteproc driver for Keystone 2 DSPs
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.
