71a3564e5f gcc 4.3.2 examines getLowerUpperIndex() and concludes that it's not
guaranteed to initialize its two last arguments.  Therefore, there is a
warning in the subsequent caller ar5416FillVpdTable(), which doesn't
initialize those arguments.

Change getLowerUpperIndex() to assign values to indexL and indexR even
in the case of assertion failure.

59efa8b517 Overhaul regulatory support:
o remove HAL_CHANNEL; convert the hal to use net80211 channels; this
  mostly involves mechanical changes to variable names and channel
  attribute macros
o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant
  with the net80211 channel available
o change api for ath_hal_init_channels: no more reglass id's, no more outdoor
  indication (was a noop), anM contents
o add ath_hal_getchannels to have the hal construct a channel list without
  altering runtime state; this is used to retrieve the calibration list for
  the device in ath_getradiocaps
o add ath_hal_set_channels to take a channel list and regulatory data from
  above and construct internal state to match (maps frequencies for 900MHz
  cards, setup for CTL lookups, etc)
o compact the private channel table: we keep one private channel
  per frequency instead of one per HAL_CHANNEL; this gives a big
  space savings and potentially improves ani and calibration by
  sharing state (to be seen; didn't see anything in testing); a new config
  option AH_MAXCHAN controls the table size (default to 96 which
  was chosen to be ~3x the largest expected size)
o shrink ani state and change to mirror private channel table (one entry per
  frequency indexed by ic_devdata)
o move ani state flags to private channel state
o remove country codes; use net80211 definitions instead
o remove GSM regulatory support; it's no longer needed now that we
  pass in channel lists from above
o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A
o simplify initial channel list construction based on the EEPROM contents;
  we preserve country code support for now but may want to just fallback
  to a WWR sku and dispatch the discovered country code up to user space
  so the channel list can be constructed using the master regdomain tables
o defer to net80211 for max antenna gain
o eliminate sorting of internal channel table; now that we use ic_devdata
  as an index, table lookups are O(1)
o remove internal copy of the country code; the public one is sufficient
o remove AH_SUPPORT_11D conditional compilation; we always support 11d
o remove ath_hal_ispublicsafetysku; not needed any more
o remove ath_hal_isgsmsku; no more GSM stuff
o move Conformance Test Limit (CTL) state from private channel to a lookup
  using per-band pointers cached in the private state block
o remove regulatory class id support; was unused and belongs in net80211
o fix channel list construction to set IEEE80211_CHAN_NOADHOC,
  IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT
o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are
  now set in the constructed net80211 channel
o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one
  of the driver-private flag bits of the net80211 channel
o move 900MHz frequency mapping into the hal; the mapped frequency is stored
  in the private channel and used throughout the hal (no more mapping in the
  driver and/or net80211)
o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the
  calculation and available in the net80211 channel
o change noise floor calibration logic to work with compacted private channel
  table setup; this may require revisiting as we no longer can distinguish
  channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used
  only to calculate status data we can live with it for now
o change ah_getChipPowerLimits internal method to operate on a single channel
  instead of all channels in the private channel table
o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency
  (always the same except for 900MHz channels)
o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory
  problems
o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now
o change ath_hal_getwirelessmodes to really return wireless modes supported
  by the hardware (was previously applying regulatory constraints)
o return channel interference status with IEEE80211_CHANSTATE_CWINT (should
  change to a callback so hal api's can take const pointers)
o remove some #define's no longer needed with the inclusion of
  <net80211/_ieee80211.h>

694be3e533 On some platforms touching the bb registers when the phy is powered
down will cause a fault.  Check the phy power state before possibly
reading from the bb, this can happen as ar5212Reset intentionally
calls ar5212GetRfgain before bringing the bb out of reset (but we
do it here and not in the caller to guard against other possible uses).

10ad9a77f3 TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
  existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
  conceivable other devices might be capable of this too in which case
  they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
  configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.

2dc7fcc48f New periodic calibration scheme needed for 11n parts that have
multiple algorithms and potentially collect multiple samples.
Instead of a single calibration interval we now have short and long
intervals; the long interval roughly corresponds to the previous
single interval.  The short interval is used to speedup collection
of samples and happens much quicker.  We make calls using the short
interval until we're told the calibration work is complete at which
point we fallback to the long interval.  In addition there is a
much longer reset interval used to flush all calibration state and
cause everthing to start anew.

With these changes you can also disable calibration entirely by
setting the long interval to zero.

3364462355 Switch to ath hal source code. Note this removes the ath_hal
module; the ath module now brings in the hal support.  Kernel
config files are almost backwards compatible; supplying

device ath_hal

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.
