-/* *** THEORY OF LOCKING ***
+/* XXX--- HOW LOCKING WORKS IN BCM43xx ---XXX
*
- * We have two different locks in the bcm43xx driver.
- * => bcm->mutex: General sleeping mutex. Protects struct bcm43xx_private
- * and the device registers. This mutex does _not_ protect
- * against concurrency from the IRQ handler.
- * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
- *
- * Please note that, if you only take the irq_lock, you are not protected
- * against concurrency from the periodic work handlers.
- * Most times you want to take _both_ locks.
+ * You should always acquire both, wl->mutex and wl->irq_lock unless:
+ * - You don't need to acquire wl->irq_lock, if the interface is stopped.
+ * - You don't need to acquire wl->mutex in the IRQ handler, IRQ tasklet
+ * and packet TX path (and _ONLY_ there.)

So OK, let's remove support for A PHYs. I never got done with it and maybe it
had to be rewritten from scratch anyway.

Stefano,
Thanks for taking the time to review the patches. As Michael wrote, the bulk of the patch comes from
his V4 code, but it's good to have it looked through.

This removal is _ONLY_ for the driver that uses V3 firmware. It will ultimately be limited to B PHYs
and removal of the A PHY stuff will happen anyway. AFAIK, support of A PHYs will be implemented
(eventually) in the V4 driver.
All suggestions implemented.
