Petersen" , "Matthew R. Ochs" , "Manoj N. Kumar" , Brian King Cc: linuxppc-dev@lists.ozlabs.org, Ian Munsie , Andrew Donnellan , Daniel Axtens From: Manoj Kumar This drop enables a future card with a device id of 0x0600 to be recognized by the cxlflash driver. As per the design, the Accelerator Function Unit (AFU) for this new IBM CXL Flash Adapter retains the same host interface as the previous generation. For the early prototypes of the new card, the driver with this change behaves exactly as the driver prior to this behaved with the earlier generation card. Therefore, no card specific programming has been added. These card specific changes can be staged in later if needed. Signed-off-by: Manoj N. Kumar Acked-by: Matthew R.
