Subject: [SCSI] bfa: Introduced generic address len pair to represent DMA
 memory chunk.

- Avoid the use of hardware defined structure bfi_sge_s for DMA
  requests in host.

- Defined a generic address len pair to represent a DMA memory chunk
  (bfi_alen_s).

Subject: [SCSI] bfa: Brocade-1860 Fabric Adapter Hardware Enablement

- Added support for Brocade-1860 Fabric Adapter.
- Made changes to support single firmware image per asic type.
- Combined bfi_cbreg.h and bfi_ctreg.h defines into bfi_reg.h with
  only minimal defines used by host.
- Added changes to setup CPE/RME Queue register offsets based on
  firmware response.
- Removed queue register offset initializations and added register offsets
  to BFI config response message.
- Added Brocade-1860 asic specific interrupt status definitions and
  mailbox interfaces.

From 775c7742adfd7726f05914198bf33eaa3b9f64bb Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Mon, 13 Jun 2011 15:52:12 -0700
Subject: [SCSI] bfa: IOC and PLL init changes for Brocade-1860 Fabric Adapter.

- Introduced IOC poll mechanism which replaces current interrupt
  based FW READY method.
- The timer based poll routine in IOC will query the ioc_fwstate
  register to see if there is a state change in FW, and sends the READY event.
- Bug fixes in the new asic PLL initialization.
- Added logic to handle CPE/RME queue interrupts before iocfc config done.
  1. Use the queue_process flag to see if iocfc configuration is done
     in INTX mode.
  2. Split the MSIX handler installation in two - one for IOC intr
     handler and the other for cpe/rme queue handler - and delay
     assigning queue handlers until iocfc config is done in MSIX mode.

From 8b070b4a022f86dd5098308e36426ce29b6b8960 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Mon, 13 Jun 2011 15:52:40 -0700
Subject: [SCSI] bfa: Brocade-1860 Fabric Adapter 16Gbs support and flash
 controller fixes.

- Added support for 16Gbps.
- Added logic to flush pending mailbox command queue when IOC is disabled.
- Fix to Halt the flash controller during fw initialization - since
  when asic blck is programmed flash controller's continuous access
  blocks f/w access to flash.
- Added new asic based card types and modified IOC get card model routine.
- Added PLL init fix to do LPU reset every time we do a memory
  initialization, since not doing so will cause LPU to be
  uninitialized during driver load.
- Added fix to Halt flash controller before PLL initialization.

From be540a991e2097c313d7304e0daaf89d68011bb9 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Mon, 13 Jun 2011 15:53:04 -0700
Subject: [SCSI] bfa: FC credit recovery and misc bug fixes.

- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.

Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
  timer calibration (around 300 miilisecs earlier). So there is a
  window if an accept comes during this time HBA would have initiated
  an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.

From: Krishna Gudipati <kgudipat@brocade.com>
Date: Mon, 13 Jun 2011 15:54:31 -0700
Subject: [SCSI] bfa: Driver initialization and model description fix

- Moved FCS initialization, which internally does the im_port creation
  as well as the scsi_host creation before bfa_init.

Once the bfa_init is complete & successful:
- Reset the FCS base port cfg params such as pwwn/nwwn and setup fc host
  params - based on the values learned during the ioc getattr request.
- Change needed to support BSG commands even on bfa init failure.
- Model description fixes for Brocade adapters.

From 5a0adaedffce91100d03fc1036dde024c8589295 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Fri, 24 Jun 2011 20:22:56 -0700
Subject: [SCSI] bfa: IOC bug fixes.

- Add logic to handle the case where PCI mapping goes away when
  IOCPF state machine is waiting for semaphore.
- Added logic to unlock hw semaphore if the previos FW boot was
  from flash based and the current FW initialization attempt is from OS.
- Added fix to update hbfails and hb_count stats during hwerror event.

From 10a07379247078448c076690657a076076bf89aa Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Fri, 24 Jun 2011 20:23:38 -0700
Subject: [SCSI] bfa: Brocade-1860 Fabric Adapter PLL init fixes.

- If flash controller is halted unconditionally, this results in
  illegal write access to flash controller register domain. Since
  flash controller registers are only accessible once s_clk is started
  - added logic to check for WGN status and halt flash controller only
  if it is already running.
- Added check to wait for flash controller halt to be completed before
  proceeding with s_clk/l_clk initializations.
- Removed unnecessary reset logic for PMM 1T memory and moved memory
  initialization after flash access enable.
- Disable Brocade-1860 asic MBOX interrupt before PLL initialization.
- Remove reset enable for S_CLK/L_CLK after both PLL initializations
  are complete.

From 3fd459804ff8e002db2671900debd0fc6dc6c443 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Fri, 24 Jun 2011 20:24:08 -0700
Subject: [SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.

- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
  from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
  in the message header and firmware modules use h/w queue ID from
  message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
  Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
  messages.  Used to translate host tag to firmware tag. bfa_lpuid()
  is changed to bfa_fn_lpu() that encodes both PCI function and port
  ID in BFI message header.

Subject: [SCSI] bfa: DMA memory allocation enhancement.

- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
  needed by all the BFA sub-modules as one contiguous chunk.

From d7be54cc5c5f6f9cb9ac67462aadda57813698b8 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Fri, 24 Jun 2011 20:24:52 -0700
Subject: [SCSI] bfa: FCS bug fixes.

- Added logic to initiate a PLOGI to the target, while processing a LOGO
  from the same target in Direct attach mode.
- Added logic to generate a FCCT Reject indicating unsupported command,
  upon receiving FCCT/FCGS requests.
- Added logic to set the fcpim in offline state and avoid any PRLI retries
  if a PRLI response is a reject with a reason Command Not Supported.
- Updated the FDMI Supported/Current speeds.
- Added logic to wait for the response  from the firmware before sending
  ACC to PLOGI and transitioning to subsequent states - while processing an
  Incoming PLOGI in online state.
- Added a wait state in the fcs_vport state machine - For case where
  FDISC is in progress and we get a vport delete request we wait for
  fdisc response and will transition to the appropriate state based on
  rsp status, else its causing both driver/fw resources to be not
  freed.
- Remove the fc_credit_recovery module param.

From 61e62e21afe469854e04546ea10b7a6f4cfd1142 Mon Sep 17 00:00:00 2001
From: Krishna Gudipati <kgudipat@brocade.com>
Date: Fri, 24 Jun 2011 20:29:07 -0700
Subject: [SCSI] bfa: Driver and BSG enhancements.

- Added a new module parameter max_xfer_size to
  set the max_sectors in the scsi_host template.
- Added logic to handle request_irq() failure so
  that msix vector resource is de-allocated immediately
  when failure happens.
- BSG enhancements to collect vHBA releated info and port log.
- Removed the workaround of incrementing the module refcnt on bsg request.
