339a7b32a3 scsi: mpi3mr: Support for Segmented Hardware Trace buffer 
Allocate segmented trace buffer if firmware advertises the capability in
IOCfacts.

Upon driver load, read the trace buffer size from driver page 1, calculate
the required segments for trace buffer, and allocate segmented buffers.
Each segment is 4096 bytes in size.

While posting driver diagnostic buffer to firmware, advertise that trace
buffer is segmented.

Make driver use the timestamp update interval value provided by firmware in

0e11f97bfd scsi: mpi3mr: struct mpi3_event_data_pcie_topology_change_list: Replace 1-element array with flexible array 
Replace the deprecated[1] use of a 1-element array in struct
mpi3_event_data_pcie_topology_change_list with a modern flexible array.

Additionally add __counted_by annotation since port_entry is only ever
accessed in loops controlled by num_entries. For example:

        for (i = 0; i < event_data->num_entries; i++) {
                handle =
                    le16_to_cpu(event_data->port_entry[i].attached_dev_handle);

fc44449411 scsi: mpi3mr: HDB allocation and posting for hardware and firmware buffers 
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
