  consumer index (CI) when RME interrupt is generated.
- Made changes to have ASIC specific hw_rspq_ack() handler.

Krishna Gudipati 775c7742ad [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.

Krishna Gudipati 111892082e [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.

Jing Huang 5fbe25c7a6 [SCSI] bfa: fix comments for c files
This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.

Krishna Gudipati f5713c5dfb [SCSI] bfa: Fix Command Queue (CPE) full condition check and ack CPE interrupt.
Fixed the issue of not acknowledging the command queue
full-to-non-full interrupt.  Implemented separate acknowledging
functions for different ASIC and interrupt mode.

Fixed the case of missing CPE interrupt by always processing the
pending requests in the completion path.
