Pull remoteproc updates from Bjorn Andersson:
"This adds an interface for configuring Qualcomm's "secure SMMU" and
adds support for booting the modem Hexagon on MSM8996.Two new debugfs entries are added in the remoteproc core to introspect
the list of memory carveouts and the loaded resource table"* tag 'rproc-v4.15' of git://github.com/andersson/remoteproc:
remoteproc: qcom: Fix error handling paths in order to avoid memory leaks
remoteproc: qcom: Drop pr_err in q6v5_xfer_mem_ownership()
remoteproc: debug: add carveouts list dump feature
remoteproc: debug: add resource table dump feature
remoteproc: qcom: Add support for mss remoteproc on msm8996
remoteproc: qcom: Make secure world call for mem ownership switch
remoteproc: qcom: refactor mss fw image loading sequence

Two different processors on a SOC need to switch memory ownership
during load/unload. To enable this, second level memory map table
need to be updated, which is done by secure layer.
This patch adds the interface for making secure monitor call for
memory ownership switching request.Acked-by: Andy Gross

In order to aid post-mortem debugging the Qualcomm platforms provide a
"memory download mode", where the boot loader will provide an interface
for custom tools to "download" the content of RAM to a host machine.The mode is triggered by writing a magic value somewhere in RAM, that is
read in the boot code path after a warm-restart. Two mechanism for
setting this magic value are supported in modern platforms; a direct SCM
call to enable the mode or through a secure io write of a magic value.In order for a normal reboot not to trigger "download mode" the magic
must be cleared during a clean reboot.Download mode has to be enabled by including qcom_scm.download_mode=1 on
the command line.Reviewed-by: Stephen Boyd

This patch converts the Qualcomm SCM driver to use the streaming DMA APIs
for communication buffers. This is being done so that the
secure_flush_area call can be removed. Using the DMA APIs will also make
the SCM32 symmetric to the coming SCM64 code.Signed-off-by: Andy Gross

HDCP driver needs to check if secure environment supports HDCP. If it's
supported, then it requires to program some registers through SCM.
Add qcom_scm_hdcp_available and qcom_scm_hdcp_req to support these
requirements.Signed-off-by: Jilai Wang

supporting a 64-bit/ARM64 implementation as well. We create a simple shim
