To be able to debug controller problems it is beneficial to allocate and configure system/host memory buffers which can be used to capture hardware and firmware diagnostic information. Add functions required to allocate and post firmware and hardware diagnostic buffers to the controller and to set up automatic diagnostic capture triggers. Captures will be triggered under the following circumstances: 1. Firmware is in FAULT state. 2. Admin commands time out. 3. Controller reset caused due to I/O timeout Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202405151758.7xrJz6rp-lkp@intel.com/ Co-developed-by: Sathya Prakash <sathya.prakash@broadcom.com> Signed-off-by: Sathya Prakash <sathya.prakash@broadcom.com> Signed-off-by: Ranjan Kumar <ranjan.kumar@broadcom.com> Link: https://lore.kernel.org/r/20240626102646.14298-2-ranjan.kumar@broadcom.com Signed-off-by: Martin K.
