- Made changes to check the flash controller status before IOC initialization.
- Made changes to poll on the FLASH_STS_REG bit to check if the flash controller
initialization is completed during the PLL init.

Made changes to resume the flash controller if it is halted before going
ahead with flash controller pause/resume logic.
Made changes to avoid clearing off the interrupts during the initial
pll initialization.

- 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.

- 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.

- 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.
