[PATCH 02/32] staging: brcm80211: new Kconfig item to enable IO reordering fix

[Arend van Spriel]

From: Roland Vossen <rvossen@broadcom.com>

bcm4716 (which includes 4717 & 4718), plus 4706 on PCIe can reorder
transactions. As a fix, a read after write is performed on certain places
in the code. Older chips and the newer 5357 family don't require this fix.

[PATCH 03/32] staging: brcm80211: replaced #ifdef __mips__ sections by W_REG_FLUSH

[Arend van Spriel]

From: Roland Vossen <rvossen@broadcom.com>

Code cleanup. A read-after-write construct is present in the code to ensure
write order for certain Broadcom chips. Those chips are: bcm4706, bcm4716,
bcm4717, bcm4718. All these chips contain a MIPS processor. This patch gets
rid of several #ifdef __mips__ sections by defining a new macro in a header
file.

[PATCH 04/32] staging: brcm80211: got rid of #ifdef __mips__ sections in hnddma.c

[Arend van Spriel]

From: Roland Vossen <rvossen@broadcom.com>

Code cleanup. Broadcom MIPS chips in big endian mode have a memory window
in which sdram contents is byte swapped. Code in hnddmac.c makes use of
this window. Reworked code so the #ifdef __mips__ is moved from .c to
.h file.

[PATCH 07/32] staging: brcm80211: remove unused functions and prototypes

[Arend van Spriel]

Several functions in wlc_bmac.c are not used in the driver and
prototypes in wlc_pub.h that have no implementation. These have
been removed.

[PATCH 08/32] staging: brcm80211: make function definitions and prototype consistent

[Arend van Spriel]

Couple of functions that are only used within wlc_channel.c have been
prototyped with static keyword. For the function definition itself this
has been added when missing.

[PATCH 09/32] staging: brcm80211: cleanup functions in nvram.c

[Arend van Spriel]

Several function in nvram.c take a pointer value which is not
actually used. These are removed and the header file contained
some other prototypes that were not implemented. As this source
file was the only one using the header file siutils.h it has been
removed.

[PATCH 10/32] staging: brcm80211: fix makefiles for building drivers in kernel

[Arend van Spriel]

The makefiles used obj-m which forcibly builds the drivers as
modules ignoring the Kconfig setting. This has been fixed in this
patch.

[PATCH 16/32] staging: brcm80211: removed counter related struct wl_cnt

[Arend van Spriel]

From: Roland Vossen <rvossen@broadcom.com>

Code cleanup. Struct wl_cnt contains all sorts of counters, but either these
were written and never read, or set to zero at initialization but never
updated. Therefore the struct and any code accessing the struct has been
removed.

[PATCH 18/32] staging: brcm80211: Fix for WPA GTK install issue in brcmfmac driver

[Arend van Spriel]

From: Sukesh Srikakula <sukeshs@broadcom.com>

Last 16 bytes of the key sent by cfg80211 needs to be swapped before
installing it to FW for TKIP encryption. This is not done for group
key in current code, which is corrected with this fix.

[PATCH 19/32] staging: brcm80211: Fix for suspend issue in brcmfmac driver

[Arend van Spriel]

From: Sukesh Srikakula <sukeshs@broadcom.com>

Currently, there are 2 callbacks registered with OS for getting
notifications when system goes to suspend/resume. Racing between
these 2 callbacks results in random suspend failures. With this fix,
we avoid registering dhd callback for suspend/resume notification
when cfg80211 is used. Relevent functionality in dhd suspend/resume
callback function is moved to cfg80211 suspend/resume functions.

[PATCH 22/32] staging: brcm80211: Optimized wl_inform_single_bss function in brcmfmac driver

[Arend van Spriel]

From: Sukesh Srikakula <sukeshs@broadcom.com>

Earlier verion of wl_inform_single_bss function is using
'cfg80211_inform_bss_frame' API for sending bss info to cfg80211.
With this patch same will be done through a more optimal
'cfg80211_inform_bss' API.

[PATCH 29/32] staging: brcm80211: cfg80211 up/down routines in brcmfmac driver are fixed

[Arend van Spriel]

From: Sukesh Srikakula <sukeshs@broadcom.com>

'__wl_cfg80211_up' & '__wl_cfg80211_down' routines are updated to correctly
set the 'wl->status' variable.

[PATCH 30/32] staging: brcm80211: Better debug support added to brcmfmac driver

[Arend van Spriel]

From: Sukesh Srikakula <sukeshs@broadcom.com>

With the current implementation there is no way to selectively enable
required debug messages, as all the messages are currently under WL_DBG.
With this fix, we are introducing several log levels which will enable
us to print only the required debug messages.
WL_ERR --> Prints error messages
WL_CONN --> Prints all debug messages pertaining to connection
management
WL_SCAN --> Prints all debug messages pertaining to scanning
WL_TRACE --> Prints all trace(Enter/Exit) sequence of cfg80211 calls
WL_INFO --> Prints all informational messages.
By default, only WL_ERR messages are enabled.

Shouldn't this be guarded with e.g. CONFIG_BCM63XX instead of
__mips__? Not every big endian mips is a broadcom ;-). I don't know if
there are further Broadcom ones, the only other I know is bcm47xx and
that one is little endian.

Is this issue specific to the wireless cores?  It sounds like this is
a general issue with the PCI(e) support on these SOCs, and probably
should be worked around in the architecture specific PCI code.

No, don't make a new kconfig option for something that everyone has to
enable as they don't know what they have on their system (think
universal kernels built by distros.)

Do this check dynamically, depending on the chip the driver is running
on, don't rely on a user to know what to do here.

So I'm not going to accept this patch, sorry.

Hi Greg,

No problem. Thanks for the feedback. There are two other patches in this 
series which depend on this one. Could you also drop the following:

[PATCH 03/32] staging: brcm80211: replaced #ifdef __mips__ sections by 
W_REG_FLUSH
[PATCH 11/32] staging: brcm80211: Kconfig fix for 'Broadcom I/O order fix'
