[PATCH 01/23] brcm80211: fmac: save bus interface structure in function 2 device

[Franky Lin]

bus interface was stored in sdio card device. The device pointer
is used as parameter of interface functions between common layer
and bus layer to make the function declaration generic for different
bus type. But the card device is a parent device layer for SDIO
function devices. It doesn't contain all contexts needed by udev.
This patch moves the shared structure to private driver data pointer
of SDIO function 2 device which is more appopriate for net device
and cfg80211 registration.

[PATCH 02/23] brcm80211: fmac: fix firmware shared structures version

[Franky Lin]

Some shared structures in fullmac have a wrong combination of
version number and declarations. This patch fixes it by upgrading
them to the latest version. This allows brcmfmac to support new
firmwares with new features.

[PATCH 05/23] bcma: add set/mask macros for 16-bit register access

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

The BCMA header only had definitions for 32-bit register access. Used
those as a template for the 16-bit flavour. Also changed them to inline
functions to be on the safe side. As offset parameter is used twice there
would be a problem when used like this: bcma_set32(core, offset++, val);

[PATCH 06/23] bcma: use static keyword for inline function declaration in bcma.h

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

Just scratching an itch here, but it makes more sense to use the
static keyword if you think about how the compiler treats inline
functions.

Instead of directly accessing the fields in struct si_pub the driver
now uses inline access functions. This is in preparation of the bcma
integration as a lot of information will be provided by bcma module.

[PATCH 10/23] brcm80211: smac: change from pci device driver to bcma device driver

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

A new bus driver called "bcma" has been introduced into the kernel tree
which considers the Broadcom AMBA chip interconnect as a bus. Each core in
the chip is a bcma device. This commit changes brcms_mac80211.c into
a bcma device driver.

[PATCH 12/23] brcm80211: smac: rename struct si_info field pbus to pcibus

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

When moving to bcma usage there are two busses in play. The pci bus
connecting the device to the host and the bcma bus connecting the
cores in the device. To distinguish this the attribute pbus has been
renamed to a more explicit name, ie. pcibus.

[PATCH 15/23] brcm80211: smac: use bcma core register access functions for 802.11 core

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

The driver now uses the bcma register access functions to read and
write the registers on the 802.11 core. The dma and phy code need
to be modified next and access to the other cores. That will be done
in coming patches.

[PATCH 16/23] brcm80211: smac: use DMA-API calls for descriptor allocations

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

Using BCMA hides the specifics about the host interface. The
driver is now using the DMA-API to do dma related calls. BCMA
provides the device object to use in the DMA-API calls.

[PATCH 19/23] brcm80211: smac: remove SI_FAST() macro usage

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

The use of SI_FAST() macro interferes with the BCMA integration as
it causes BCMA and aiutils.c to get out of sync on what the current
core is. When everything is using BCMA we will try to add SI_FAST
functionality to BCMA to avoid unnecessary core switching.

[PATCH 20/23] brcm80211: smac: replace ai_corereg() function with ai_cc_reg()

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

The ai_corereg() function is only used in the driver to safely
access the chipcommon core. The function has been renamed to
ai_cc_reg() removing the need to provide a core index parameter.

[PATCH 23/23] brcm80211: smac: use bcma core access functions in nicpci.c

[Franky Lin]

From: Arend van Spriel <arend@broadcom.com>

Code in nicpci.c now uses the PCI(E) core as provided by the BCMA
bus driver to configure that core.

What is an advantage of static inline over define?

Hi Rafał,

Apart from the example given in the commit message the CodingStyle
documentation states a preference for inline functions. One advantage I
can come up with is type checking by the compiler.

Hi,

nice patches for brcmsmac. I tried them on my bcm4716 device (wireless
core on the system bus), but brcmsmac does not work there, I am getting
a kernel oops. aiutils.c does does not work for SoCs e.g.
ai_setcoreidx() does not handle that all cores are mapped on SoCs at the
same time, just under different addresses. I hope you are working on
removing aiutils.c and moving the parts missing in bcma into it.

Re: [PATCH 05/23] bcma: add set/mask macros for 16-bit register access

Possible to use proper compiler checks and easier to read. Better to
avoid C preprocesor until it's absolutely necessary to use it, makes it
a lot easier for everyone.

Hi Hauke,

Thanks for the compliment ;-) Let me explain the steps set out to get
brcmsmac using bcma,

1) convert to use bcma functions in all brcmsmac source files.
2) cleanup aiutils.c as it is redundant.
3) look for opportunities to move code to bcma (eg. nicpci.c, srom.c)

For steps 1) and 2) we have patches queued up of which the first batch
was submitted. Keep an eye on the mailing list for more to come ;-)

Thanks for explaining, compiler errors should be indeed nicer. Thanks
for patch :)
