Suganath Prabu ba630ea068 scsi: mpt3sas: Support MEMORY MOVE Tool box command
Host uses the Memory Move Tool to copy data from any source/destination
combination of system memory and IOC memory.

Memory Move Tool box request contains two SGE fields, First SGE field must
contains the source buffer details described by an MPI Simple SGE.  The
second SGE field must contains the destination buffer details described by
an MPI Simple SGE.

 Source   ->   Destination

1. IOC    ->   IOC    (Both the SGE's will be filled by application)

2. HOST   ->   HOST   (Both the SGE's will be filled by the host,
               application should give sgl_offset to first SGE offset)

3. IOC    ->   HOST   (Application will fill the first SGE and set the
               sgl_offset to second SGE and hence driver fills
               the second SGE)
4. HOST   ->   IOC    (Application will fill IOC buffer information in the
               first SGE and set the sgl_offset to second SGE.
               Then driver will fill the second SGE with Host buffer
               information and just before posting the command to the
               firmware, driver will swap these two SGEs so that first
               SGE contains the HOST buffer information and second SGE
               contains the IOC information.

Driver has to take care only of the 4th case, other three cases are by
default supported by the current driver design.

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.
