Qualcomm crypto engine allows for IV registers and status register to be concatenated to the output. This option is enabled by setting the RESULTS_DUMP field in GOPROC register. This is useful for most of the algorithms to either retrieve status of operation or in case of authentication algorithms to retrieve the mac. But for ccm algorithms, the mac is part of the output stream and not retrieved from the IV registers, thus needing a separate buffer to retrieve it. Make enabling RESULTS_DUMP field optional so that algorithms can choose whether or not to enable the option. Note that in this patch, the enabled algorithms always choose RESULTS_DUMP to be enabled. But later with the introduction of ccm algorithms, this changes.

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.
