In order to be able to start the adsp listener for audiopd using adsprpcd, we need to add the corresponding ioctl for creating a static process. On that ioctl call we need to allocate the heap. Allocating the heap needs to be happening only once and needs to be kept between different device open calls, so attach it to the channel context to make sure that remains until the RPMSG driver is removed. Then, if there are any VMIDs associated with the static ADSP process, do a call to SCM to assign it. And then, send all the necessary info related to heap to the DSP.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
