The CONFIG_BCM947XX configuration variable was designed for use by the
embedded device used by the OpenWRT project. The device has been shifted
to the ssb driver in bcm43xx-mac80211 and will not be used with SoftMAC.
Accordingly, this "dead" configuration variable is removed.

In code manipulating the TM State Low register of 802.11 cores, two
different magic numbers are used to reference the 'G Mode Enable' bit.
One of these, 0x20000000, is clear, but the other, (0x800 << 18), is not.
This patch replaces both types with a defined constant. In addition, two
bits in the TM State High registers are given definitions to help in
following the code.

The specifications for the bcm43xx driver have been modified. This
patch incorporates these changes in the code, which results in the
BCM4311 and BCM4312 working. The name of one of the PHY parameters,
previously known as "version", has been changed to "analog", short for
"analog core version" .

Some versions of the bcm43xx chips only support 30-bit DMA, which means
that the descriptors and buffers must be in the first 1 GB of RAM. On
the i386 and x86_64 architectures with more than 1 GB RAM, an incorrect
assignment may occur. This patch ensures that the various DMA addresses
are within the capability of the chip. Testing has been limited to x86_64
as no one has an i386 system with more than 1 GB RAM.

The current bcm43xx driver ignores any wireless-enable switches on mini-PCI
and mini-PCI-E cards. This patch implements a new routine to interrogate the
radio hardware enabled bit in the interface, logs the initial state and any
changes in the switch (if debugging enabled), activates the LED to show the
state, and changes the periodic work handler to provide 1 second response
to switch changes and to account for changes in the periodic work specs.

Rewrite of the bcm43xx initialization routines.
This fixes several issues:
* up-down-up-down-up... stale data issue
(May fix some DHCP issues)
* Fix the init vs IRQ handler race (and remove the workaround)
* Fix init for cards with multiple cores (APHY)
As softmac has no internal PHY handling (unlike dscape),
this adds the file "phymode" to sysfs.
The active PHY can be selected by writing either a, b or g
to this file. Current PHY can be determined by reading from it.
* Fix the controller restart code.
Controller restart can now also be triggered through
echo 1 > /debug/bcm43xx/ethX/restart

Suspend MAC (and make MAC-suspend refcounting) when doing
long periodic work.
On long periodic work, we disable IRQs on the device, so
we don't want the MAC to stay operating and probably miss
packets due do non-delivery of interrupts.
