Hauke Mehrtens 1f03bf06e4 bcma: fix invalid PMU chip control masks
Commit b9562545ef ("bcma: complete workaround for BCMA43224 and
BCM4313") introduced the wrong masks for setting the chip control
registers - the "mask" parameter is inverse.

It should be the mask of bits *not* changed, which is admittedly a bit
non-intuitive.

The incorrect mask not only causes the driver to not work correctly on
the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the
state persists over a soft reset, causing the next boot to not
necessarily see the device correctly.

Hauke Mehrtens d8f1bd2ffc bcma: fix regression in interrupt assignment on mips
The wrong interrupts where assigned to the cores in
bcma_core_mips_init(). This caused at least my serial console not to
response to any input.

This was caused by this patch which changed the order of the cores in
the list:

    bcma: add new cores at the end of list

This should be fixed properly later so that the correct interrupt
numbers are assigned to the cores independently from the ordering of
the list. This patch restores the old behavior again. I will look into
the problem more deeply later.

I also changed the order of the list with the cores and their assigned
interrupt number which gets printed to the log. Now they are printed in
the same order like all the other lists of cores and like it was done
before the patch which changed the order.

The list of devices where nothing has to be done in
bcma_pmu_resources_init() and bcma_pmu_workarounds() is longer as all
the SoCs are missing there and some new devices will be added in some
time later. This patch changes the default case to just log on debug
level and also let the other devices which do not need any special
handling into the default case, instead of adding the missing 8 SoC
chip ids.

 "Ok, everything from here on out will be bug fixes."

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

Hauke Mehrtens 32998cc96a bcma: use fallback sprom if no on chip sprom is available
bcma should check for a fallback sprom every time it can not find a
sprom on the card itself or a normal external sprom mapped into the
memory of the chip. When otp sprom support was introduced it tried to
read out the sprom from the wireless chip also if no otp sprom was
available. This caused a Data bus error in bcma_sprom_get() when
reading out the sprom for the SoC.

This fixes a regression introduced in commit:

Paul Gortmaker 58f743ee06 bcma: fix build error on MIPS; implicit pcibios_enable_device
The following is seen during allmodconfig builds for MIPS:

drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration
of function 'pcibios_enable_device' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1

Most likey introduced by commit 49dc957715

    "bcma: add PCIe host controller"

Add the header instead of implicitly assuming it will be present.
Sounds like a good idea, but that alone doesn't fix anything.

The real problem is that the Kconfig has settings related to whether
PCI is possible, i.e.

  config BCMA_HOST_PCI_POSSIBLE
        bool
        depends on BCMA && PCI = y
        default y

  config BCMA_HOST_PCI
        bool "Support for BCMA on PCI-host bus"
        depends on BCMA_HOST_PCI_POSSIBLE

...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't
have any dependencies on the above.  Add one.

Arend van Spriel 10d8493cd9 bcma: add support for on-chip OTP memory used for SPROM storage
Wireless Broadcom chips can have either their SPROM data stored
on either external SPROM or on-chip OTP memory. Both are accessed
through the same register space. This patch adds support for the
on-chip OTP memory.

Tested with:
BCM43224 OTP and SPROM
BCM4331 SPROM
BCM4313 OTP

This patch is in response to linux-wireless thread [1].

Arend van Spriel 4ac887cfda bcma: return error in bcma_sprom_get() when fallback fails
When not SPROM is available a fallback mechanism is used. However,
when that fails the code currently continues. This patch assures
that the bcma_sprom_get() function aborts when that happens.

Hauke Mehrtens a027237a56 bcma: add support for sprom not found on the device
On SoCs the sprom is stored in the nvram in a special partition on the
flash chip. The nvram contains the sprom for the main bus, but
sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
sprom from the nvram and provide it to the bcma code.
