Pull remoteproc updates from Bjorn Andersson:
 "This adds support for the STM32 remoteproc, additional i.MX platforms
  with Cortex M4 remoteprocs and Qualcomm's QCS404 Compute DSP.

  Also initial support for vendor specific resource table entries and
  support for unprocessed Qualcomm firmware files"

remoteproc: stm32: fix building without ARM SMCC

2019-07-08T14:05:50+00:00

When compile testing this driver without SMCC support enabled,
we get a link error:

drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_start':
stm32_rproc.c:(.text+0x776): undefined reference to `__arm_smccc_smc'
drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_stop':
stm32_rproc.c:(.text+0x92c): undefined reference to `__arm_smccc_smc'

Make the actual call to arm_smccc_smc conditional on the Kconfig
symbol controlling its implementation.

remoteproc: qcom: q6v5-mss: Fix build error without QCOM_MDT_LOADER

2019-07-04T18:20:36+00:00

If QCOM_Q6V5_MSS is set but QCOM_MDT_LOADER is not,
building will fails:

qcom_q6v5_mss.c:(.text+0x3260): undefined reference to `qcom_mdt_read_metadata'

Add QCOM_MDT_LOADER dependency for QCOM_Q6V5_MSS.

remoteproc: copy parent dma_pfn_offset for vdev

2019-07-02T02:09:01+00:00

When preparing the subdevice for the vdev, also copy dma_pfn_offset
since this is used for sub device dma allocations. Without that, there
is incoherency between the parent dma settings and the childs one,
potentially leading to dma_alloc_coherent failure (due to phys_to_dma
using dma_pfn_offset for translation).

remoteproc: qcom: q6v5-mss: Support loading non-split images

2019-07-02T02:02:32+00:00

In some software releases the firmware images are not split up with each
loadable segment in it's own file. Check the size of the loaded firmware
to see if it still contains each segment to be loaded, before falling
back to the split-out segments.

remoteproc: stm32: add an ST stm32_rproc driver

2019-06-30T04:00:02+00:00

This patch introduces a new remoteproc driver to control Cortex-M4
co-processor of the STM32 family.
It provides with the following features:
- start and stop
- dedicated co-processor memory regions registration
- coredump and recovery

remoteproc: Use struct_size() helper

2019-06-29T19:04:07+00:00

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct resource_table {
	...
        u32 offset[0];
} __packed;

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

So, replace the following form:

table->num * sizeof(table->offset[0]) + sizeof(struct resource_table)

with:

struct_size(table, offset, table->num)

This code was detected with the help of Coccinelle.

remoteproc: add vendor resources handling

2019-06-29T19:02:17+00:00

In order to allow rproc backend to handle vendor resources such as in
OpenAMP, add a handle_rsc hook. This hook allow the rproc backends to
handle vendor resources as they like. The hook will be called only for
vendor resources and should return RSC_HANDLED on successful resource
handling, RSC_IGNORED if resource was ignored, or a negative value on
error.
