Title:
  wl12xx borked after one up/down cycle

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  SRU:

  Impact: wifi on the Pandaboard is not working after doing one "up/down
  cycle". This can either be a "ifconfig wlan0 up && ifconfig wlan0
  down", or something else that triggers firmware booting inside wl12xx

  This is wlan output after a cold boot:
  wlcore: firmware booted (Rev 6.3.10.0.133)
  wlan0: authenticate with a0:f3:c1:46:2c:e4
  wlan0: send auth to a0:f3:c1:46:2c:e4 (try 1/3)
  wlan0: authenticated
  wlan0: associate with a0:f3:c1:46:2c:e4 (try 1/3)
  wlan0: RX AssocResp from a0:f3:c1:46:2c:e4 (capab=0x431 status=0 aid=2)
  wlan0: associated
  cfg80211: Calling CRDA for country: DE
  cfg80211: Regulatory domain changed to country: DE
  cfg80211:   (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
  cfg80211:   (2400000 KHz - 2483500 KHz @ 40000 KHz), (N/A, 2000 mBm)
  cfg80211:   (5150000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm)
  cfg80211:   (5250000 KHz - 5350000 KHz @ 40000 KHz), (N/A, 2000 mBm)
  cfg80211:   (5470000 KHz - 5725000 KHz @ 40000 KHz), (N/A, 2698 mBm)
  cfg80211:   (57240000 KHz - 65880000 KHz @ 2160000 KHz), (N/A, 4000 mBm)
  wlcore: Association completed.

  while this is what happens after a warm reboot or after an ifdown/ifup cycle:
  wlcore: down
  wlcore: ERROR timeout waiting for the hardware to complete initialization
  wlcore: ERROR timeout waiting for the hardware to complete initialization
  wlcore: ERROR timeout waiting for the hardware to complete initialization
  wlcore: ERROR firmware boot failed despite 3 retries

  Both S and T are affected, but:

  * patches 1 and 2 are a prerequisite and are required for S only (since T already has them)
  * patches 3 and 4 are the real fix, and ATM are queued in tmlind's  omap-for-v3.13/fixes-take4 (git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap.git)

  Fix: apply the attached patches and recompile

  Test case: boot the patched kernel, check that wifi is on, reboot the
  board and check again that wifi availability
