[PATCH] brcmfmac: use separate firmware for 43430 revision 2

[PATCH] brcmfmac: use separate firmware for 43430 revision 2

[Mikhail Rudenko]

A separate firmware is needed for Broadcom 43430 revision 2.  This
chip can be found in e.g. certain revisions of Ampak AP6212 wireless
IC. Original firmware file from IC vendor is named
'fw_bcm43436b0.bin', but brcmfmac and also btbcm drivers report chip
id 43430, so requested firmware file name is
'brcmfmac43430b0-sdio.bin' in line with other 43430 revisions.

That is bad naming. There already is a 43436 USB device.

As always there is the question about who will be publishing this 
particular firmware file to linux-firmware.

The above mentioned file can be easily found by web search. Also, the
corresponding patch for the bluetooth part has just been accepted
[1]. Is it strictly necessary to have firmware file in linux-firmware in
order to have this patch accepted?

This patch is a bit in the gray area. We have a rule that firmware
images should be in linux-firmware, but as the vendor won't submit one
and I assume the license doesn't approve the community submit it either,
there is not really any solution for the firmware problem.

On the other hand some community members have access to the firmware
somehow so this patch is useful to the community, and I think taking an
exception to the rule in this case is justified. So I am inclined
towards applying the patch.

Thoughts? I also have another similar patch in the queue:

At the moment I am not sure which company/division is shipping the 43430 
rev 2 or 43436. Having it in linux-firmware is still preferred.

As an end-user community members using the device are allowed to use the 
firmware to run on that device. So I tend to agree with you.

I will review both and comment/ack them.

Please follow the existing strategy, ie. support higher chip revisions 
unless proven otherwise. So 0xFFFFFFFC iso 0x00000004.
