[PATCH v1 2/8][SCSI] mpt3sas: Clear PFA Status on SGPIO when PFA Drive is Removed or Replaced

[Sreekanth Reddy]

Added code to send an SEP message that turns off the Predictive
Failure LED when a drive is removed (if Predictive Failure LED was turned on).

Added a new flag 'pfa_led_on' per device that tracks the status of Predictive
Failure LED. When the drive is removed, this flag is checked and
sends an SEP message to turn off the respective Predictive Failure LED.

[PATCH v1 4/8][SCSI] mpt3sas: MPI2.5 Rev H (2.5.3) specifications

[Sreekanth Reddy]

Below is the change set in MPI2.5 Rev H specification and 2.00.32 header files
1) Added reserved fields to IO Unit Page 7 for future use.
2) Added optional functionality to IOCInit Request so that
   the host may specify a separate base address for each
   Reply Descriptor Post Queue. IOC support for this is
   indicated using a new IOCCapabilities bit in the IOCFacts Reply.
3) Added Toolbox Console Text Display Tool
   The host uses the Console Text Display Tool to send a string to
   IOC's Console using different console types (eg: UART serial terminal or Ethernet terminal).
4) Firmware images can now be signed using an encrypted hash.
5) Added MPI2_SAS_OP_TRANSMIT_PORT_SELECT_SIGNAL
6) Added more details about configuration page restrictions when Host Based Discovery is enabled
   Enabling host based discovery affects the availability of some configuration pages and events.
   The SAS Expander, SAS Device, and SAS Enclosure configuration  pages are not available from the IOC.
   The IOC returns an error status to any Configuration Request message attempting to access these pages.
   The IOC does not send the SAS Discovery Event, the SAS Topology Change List Event, or
   the SAS Enclosure Device Status Change Event when host based discovery is enabled.
7) Bit 13 of the SAS IO Unit Page 1 ControlFlags field is now obsolete.
   It was used to enable limiting direct attached SATA maximum link rate to 1.5 Gbps.

[PATCH v1 7/8][SCSI] mpt3sas: Added Reply Descriptor Post Queue (RDPQ) Array support

[Sreekanth Reddy]

Up to now, Driver allocates a single contiguous block of memory
pool for all reply queues and passes down a single address in the
ReplyDescriptorPostQueueAddress field of the IOC Init Request
Message to the firmware.

When firmware receives this address, it will program each of the
Reply Descriptor Post Queue registers, as each reply queue has its
own register. Thus the firmware, starting from a base address it
determines the starting address of the subsequent reply queues
through some simple arithmetic calculations.

The size of this contiguous block of memory pool is directly proportional
to number of MSI-X vectors and the HBA queue depth. For example higher
MSIX vectors requires larger contiguous block of memory pool.

But some of the OS kernels are unable to allocate this larger
contiguous block of memory pool.

So, the proposal is to allocate memory independently for each
Reply Queue and pass down all of the addresses to the firmware.
Then the firmware will just take each address and program the value
into the correct register.

When HBAs with older firmware(i.e. without RDPQ capability) is used
with this new driver then the max_msix_vectors value would be set
to 8 by default.

Change set in v1:

1. Declared the _base_get_ioc_facts() functions at the beginning of the mpt3sas_base.c file
instead of moving all these functions before mpt3sas_base_map_resources() function
        a. _base_wait_for_doorbell_int()
        b. _base_wait_for_doorbell_ack()
        c. _base_wait_for_doorbell_not_used()
        d. _base_handshake_req_reply_wait()
        e. _base_get_ioc_facts()

2. Initially set the consistent DMA mask to 32 bit and then change it to 64 bit mask
after allocating RDPQ pools by calling the function _base_change_consistent_dma_mask.
This is to ensure that all the upper 32 bits of RDPQ entries's base address to be same.

3. Reduced the redundancy between the RDPQ and non-RDPQ support in these following functions
        a. _base_release_memory_pools()
        b. _base_allocate_memory_pools()
        c. _base_send_ioc_init()
        d. _base_make_ioc_operational()
