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

- 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.

- 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.

- 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.

- 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.

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 */.

We have flattened the BFA hierarchy and also reduced the number of
source and header files we used to have earlier.

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.
