net/mlx5: FPGA, Add basic support for Innova Mellanox Innova is a NIC with ConnectX and an FPGA on the same board. The FPGA is a bump-on-the-wire and thus affects operation of the mlx5_core driver on the ConnectX ASIC. Add basic support for Innova in mlx5_core. This allows using the Innova card as a regular NIC, by detecting the FPGA capability bit, and verifying its load state before initializing ConnectX interfaces. Also detect FPGA fatal runtime failures and enter error state if they ever happen. All new FPGA-related logic is placed in its own subdirectory 'fpga', which may be built by selecting CONFIG_MLX5_FPGA. This prepares for further support of various Innova features in later patchsets. Additional details about hardware architecture will be provided as more features get submitted.

net/mlx5: FPGA, Add SBU bypass and reset flows The Innova FPGA includes shell hardware and Sandbox-Unit (SBU) hardware. The shell hardware is handled by mlx5_core itself, while the SBU is handled by a client driver. Reset the SBU to a well-known initial state when initializing a new device, and set the FPGA to bypass mode when uninitializing a device. This allows the client driver to assume that its device has been reset when a new device is detected. During SBU reset, the FPGA is put into SBU-bypass mode. In this mode packets do not pass through the SBU, so it cannot affect the network data stream at all. A factory-image does not have an SBU, so skip these flows.

net/mlx5: FPGA, Add SBU infrastructure 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>
