This target IRAM recovery feature support is to copy target IRAM contents available at ATH10K_MEM_REGION_TYPE_REG to host memory for back up after firmware loaded. Target IRAM contents are copied to wmi memory chunks allocated for the WMI_IRAM_RECOVERY_HOST_MEM_REQ_ID and provide the wmi chunks address to the firmware through wmi init command. If firmware detects andy IRAM corruption through periodic checksum validation, It will download the IRAM contents back from the provided wmi memory chunks address using hif_memcpy. This IRAM recovery feature prevent target assert in case of unexpected target IRAM corruptions. This patch also introduce a new feature flag 'iram-recovery' for backward compatibility.

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.
