-*
-* Portions of the development of this software were funded by
-* Intersil Corporation as part of PRISM(R) chipset product development.
-*
-* --------------------------------------------------------------------
-*
-* This file implements functions that correspond to the prism2/hfa384x
-* 802.11 MAC hardware and firmware host interface.
-*
-* The functions can be considered to represent several levels of
-* abstraction. The lowest level functions are simply C-callable wrappers
-* around the register accesses. The next higher level represents C-callable
-* prism2 API functions that match the Intersil documentation as closely
-* as is reasonable. The next higher layer implements common sequences
-* of invokations of the API layer (e.g. write to bap, followed by cmd).
-*
-* Common sequences:
-* hfa384x_drvr_xxx Highest level abstractions provided by the
-* hfa384x code. They are driver defined wrappers
-* for common sequences. These functions generally
-* use the services of the lower levels.
-*
-* hfa384x_drvr_xxxconfig An example of the drvr level abstraction. These
-* functions are wrappers for the RID get/set
-* sequence. They call copy_[to|from]_bap() and
-* cmd_access(). These functions operate on the
-* RIDs and buffers without validation. The caller
-* is responsible for that.
-*
-* API wrapper functions:
-* hfa384x_cmd_xxx functions that provide access to the f/w commands.
-* The function arguments correspond to each command
-* argument, even command arguments that get packed
-* into single registers. These functions _just_
-* issue the command by setting the cmd/parm regs
-* & reading the status/resp regs. Additional
-* activities required to fully use a command
-* (read/write from/to bap, get/set int status etc.)
-* are implemented separately. Think of these as
-* C-callable prism2 commands.
-*
-* Lowest Layer Functions:
-* hfa384x_docmd_xxx These functions implement the sequence required
-* to issue any prism2 command. Primarily used by the
-* hfa384x_cmd_xxx functions.
-*
-* hfa384x_bap_xxx BAP read/write access functions.
-* Note: we usually use BAP0 for non-interrupt context
-* and BAP1 for interrupt context.
-*
-* hfa384x_dl_xxx download related functions.
-*
-* Driver State Issues:
-* Note that there are two pairs of functions that manage the
-* 'initialized' and 'running' states of the hw/MAC combo. The four
-* functions are create(), destroy(), start(), and stop(). create()
-* sets up the data structures required to support the hfa384x_*
-* functions and destroy() cleans them up. The start() function gets
-* the actual hardware running and enables the interrupts. The stop()
-* function shuts the hardware down. The sequence should be:
-* create()
-* .
-* . Self contained test routines can run here, particularly
-* . corereset() and test_hostif().
-* .
-* start()
-* .
-* . Do interesting things w/ the hardware
-* .
-* stop()
-* destroy()
-*
-* Note that destroy() can be called without calling stop() first.

- unless at least 5us elapses between accesses. The safest choice

-
- What this means:
-
- We have to serialize ALL BAP accesses, and furthermore, add a 5us
- delay after access if we're using a PCI platform.
-
- Unfortunately, this means we have to lock out interrupts througout
- the entire BAP copy.
-
- It remains to be seen if "BAP access" means "BAP setup" or the more
- literal definition of "copying data back and forth" I'm erring for
