Add interface to initialize and interact with Innova FPGA SBU connections. A client driver may use these functions to set up a high-speed DMA connection with its SBU hardware logic, and send/receive messages over this connection. A later patch in this patchset will make use of these functions for Innova IPSec offload in mlx5 Ethernet driver. Add commands to retrieve Innova FPGA SBU capabilities, and to read/write Innova FPGA configuration space registers and memory, over internal I2C. At high level, the FPGA configuration space is divided such: 0x00000000 - 0x007fffff is reserved for the SBU 0x00800000 - 0xffffffff is reserved for the Shell 0x400000000 - ... is DDR memory A later patchset will add support for accessing FPGA CrSpace and memory over a high-speed connection. This is the reason for the ACCESS_TYPE enumeration, which currently only supports I2C. Signed-off-by: Ilan Tayari <ilant@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
