9ce3bf225e remoteproc: Use size_t type for len in da_to_va
With upcoming changes in elf loader for elf64 support, section size will
be a u64. When used with da_to_va, this will potentially lead to
overflow if using the current "int" type for len argument. Change
da_to_va prototype to use a size_t for len and fix all users of this
function.

2d02d15804 remoteproc: Remove null character write of shared mem
remoteproc is writing '\0' in the shared mem region. This
region is shared among multiple clients that are also trying
to read. Hence they miss first character.

Remove this null character write, as this mem area is
supposed to be Read only.

Further during every subsystem reboot, this region is
initialized with default, hence no need to write this
region.

0f21f9cc9d remoteproc: Merge rproc_ops and rproc_fw_ops
There are currently a few different schemes used for overriding fw_ops
or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default
ELF-loader symbols so that they can be assigned by the drivers.

To keep backwards compatibility with the "default" case, a driver not
specifying the "load" operation is assumed to want the full ELF-loader
suit of functions.

6de1a507c4 remoteproc: qcom_wcnss: Fix circular module dependency
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.

remoteproc node and make the edge life cycle follow the running state of

This bond is necessary to clean up the smd state when the remote

in a controlled fasion.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

$ modinfo drivers/remoteproc/qcom_wcnss.ko | grep alias
