Fix some endian issue. __BIGENDIAN is not defined and it needs to be
replaced with __BIG_ENDIAN. Also fixed a bug in bit field access.
These two issues were reported by Dan Carpenter.Signed-off-by: Jing Huang

- Added dconf (Driver Config) BFA sub-module.
- The dconf sub-module provides interfaces and manages flash writes
to the flash DRV parition.
- dconf sub-module also ensures that the whole 64K DRV partition is updated
on a flash write.Signed-off-by: Krishna Gudipati

- 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.Signed-off-by: Krishna Gudipati

- Updated/added data structures and definitions to support FAA protocol.
- Modified the IOC state machine to support FAA.
- Introduced FAA feature configuration - enable/disable/query.Signed-off-by: Krishna Gudipati

- 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.Signed-off-by: Krishna Gudipati

- Added ASIC block configuration APIs:
- to create/delete/update the physical functions
- to do adapter/port mode configuration
- to query the current ASIC block configuration.Signed-off-by: Krishna Gudipati

- 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.Signed-off-by: Krishna Gudipati

- 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.Signed-off-by: Krishna Gudipati

- 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.Signed-off-by: Krishna Gudipati

Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get
a notification and hence are not cleanly shutdown. So registers holding
driver/IOC state information are not reset back to valid disabled/parking
values. This causes subsequent driver initialization to hang during kdump
kernel boot.Fix description: during the initialization of first PCI function, reset
corresponding register when unclean shutown is detect by reading chip
registers. This will make sure that ioc/fw gets clean re-initialization.Signed-off-by: Jing Huang

- Move fw trace save logic to bfa_ioc_sm_fail_entry(),
so that fw trace is saved irrespective of the cause of the failure.
- Make bfa_ioc_sm_fail() a failure parking state.
- Rename bfa_ioc_sm_initfail() to a more appropriate bfa_ioc_sm_fail_retry()
as it is no longer a parking state.Signed-off-by: Krishna Gudipati
