This patch extends the use of the brcmfmac driver with support for
chipsets with a USB host interface. The first chipsets supported are
the bcm43235, bcm43236, and bcm43238 for which firmware has been
submitted.
This driver change has been successfully built for x86, x86_64,
ppc64, arm_le, and mips_be.
It has been tested successfully on x86 and x86_64.

The set_template commands now takes the role_id as
parameter.
Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.
Update WL127X_FW_NAME/WL128X_FW_NAME.
(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

This reverts commit 393fb560d3.
Commit b6ad726 ("mmc: core: Prevent too long response times
for suspend") fails the suspend if the mmc host can't be
claimed before suspend. As the host is claimed by us as long
as the chip is powered on, suspend will always fail.
Revert to claiming the sdio bus only when needed.

wl1271_tx_update_filters() is used as some workaround
to open filters while roaming on the same channel.
However, it doesn't handle roaming to a different channel,
and it might also sleep in the tx path, which is a bug.
With the new auth/assoc redesign, roaming is much simpler,
and this function is not needed anymore.

with the new auth/assoc redesign, we get CHANGED_BSSID
indication before CHANGED_ASSOC indication, while our
CHANGED_BSSID handling block assumes we are already
associated.
Fix it by checking we are either in ibss mode, or
already associated.

Add a testmode command to retrieve the BD_ADDR that is stored in the
Fuse ROM in newer PGs. In old PGs this operation is not supported.
The caller can then derive the MAC addresses from it.
Signed-off-by: Luciano Coelho <coelho@ti.com>
Add support for two MAC addresses. If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.
If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM. If it does, we read it and derive
the two subsequent addresses for WLAN.
During production, 3 addresses are reserved per device. The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.
This patch has some code by Igal and Arik (squashed from internal
patches).

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version. We need to know the MAC address
during probe, because that's when we register our HW with mac80211.
To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time. We power the chip on
briefly in order to do that.

Up till now we only needed to access the partition table in boot.c.
But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.
Thus, we move the partition table to io.c and export it via io.h. It
makes more sense to have it in the io part anyway.

In some cases a race condition can happen if we don't cancel any

work and clear the wl->flags bitmask. Also clean up the wl elements
after powering off.

The interrupt threaded handler exits immediately if the driver's state
is WL1271_STATE_OFF. As a result, the interrupt status is not read. If
the interrupt is level triggered, it will be fired again.
Fix this by disabling interrupts before setting the state to OFF.

When stopping plt, the chip is powered off before all current work items
are flushed and interrupts are disabled. This might introduce a race in
which the driver tries to communicate with a powered off chip.
Fix this by powering off the device only after interrupts are disabled
and all work items are flushed.

__wl1271_plt_stop is called from both wl1271_plt_stop and
wl1271_unregister_hw. While wl1271_plt_stop acquires a mutex,
wl1271_unregister_hw does not.

wl1271_unregister_hw.
