brcmfmac: Updating Broadcom/Cypress Wifi/BT firmware

[Stefan Wahren]

Hi,
i wanted to know, if there are any plans to update the Broadcom/Cypress firmware under:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

As BCM2835 maintainer i'm interested in the following files:

brcm/brcmfmac43430-sdio.bin
brcm/brcmfmac43455-sdio.bin
brcm/brcmfmac43430-sdio.txt
brcm/BCM43430A1.hcd

It would be nice to have those files in this repository, so kernelci could fetch it from there.

Best regards
Stefan

To my knowledge (just checked ;-) ) these are already in the repository.

We do not distribute these .txt files aka nvram files as they are board 
specific and no good solution to express that in the filename.

The BT side is not handled by us. Might be different within Cypress though.

i know, but the subject was about updating. These files are from 
2015/2016 and contains a lot of issues (including CVE-2016-0801 
CVE-2017-0561 CVE-2017-9417).

AFAIK the latest version of brcmfmac43430-sdio.bin was from October 2017 
[1].

Just an an indicator, the Raspberry Pi supplied firmware, which I
believe is now a standard build (no customisations) from the Cypress
firmware source tree, is dated Oct 2017, so somewhat newer than that
in firmware. It also has a some bug fixes in, Stefan has flagged
some of the security ones, but there are others.
