- 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.

- 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.
