Perhaps some of the cfgs could have different NUM_OF_SDI/NUM_OF_SDO (all are currently 4)

Consider renaming these to NUM_OF_MISO/MOSI (or something in this vein), since the VIP could have MOSI as input or output depending on the mode in the future.

This commit fixes the read and write test for the offload mode of the test_lanes. The DDR read was removed by accident in latest commit. It also fixes the mask and the num of active lanes. Signed-off-by: Carlos Souza <[email protected]>
Both tests were not generic regarding the sdi_lane_mask. They were relying on the default value, which is not guaranteed that it is going to enable all lanes. Added instructions to change the sdi_lane_mask before executing the tests for the FIFO and Offload modes. Signed-off-by: Carlos Souza <[email protected]>
Update the version of the spi engine to 2.0 since it is not backwards compatible. Signed-off-by: Carlos Souza <[email protected]>
