A separate firmware is needed, for Broadcom 43430 revision 4. This
chip can be found on e.g. certain revisions of Raspberry Pi Zero 2 W.
Original firmware file from IC vendor is named 'brcmfmac43436-sdio.bin',
but brcmfmac and also btbcm drivers report chip id 43430, so requested
firmware file name is 'brcmfmac43430c0-sdio.bin' in line with other
43430 revisions.

Hi,
i'm not sure about all these mappings. All i can say is that the wifi
interface of the RPi Zero 2 cames up with this patch.

I am also a bit confused. The subject mentions revision 4, but your log
shows 43430/2. Took some digging but found that numerical rev 2 matches
'b0' and rev 3 matches 'b1'. The BT part is unknown territory for me so can
not clarify things there.

Arend

my patch based on a similar patch [1] by Mikhail Rudenko. I falsely
assumed that the Ampak AP6212 and Raspberry Pi Zero 2 W are using
different wifi chips. But now it i think they are identical. If i grep
the firmware blob for the Raspberry Pi Zero 2 W, i getting this:
# strings firmware.bin | grep 4343
43436b0-roml/sdio-g-pool-p2p-pno-pktfilter-keepalive-aoe-mchan-proptxstatus-ampduhostreorder-lpc-wl11u-fmc-wepso-anqpo-srmem-srfast-11nprop-ob-ndoe-rssiindur-bcol-gtr-mfp-sdiorxenhance-extsae
Version: 9.88.4.65 (test) (f149b32@shgit) (r679549) CRC: 3e0bc4b6 Date:
Fri 2020-10-09 14:45:07 CST Ucode Ver: 1043.20742 FWID: 01-f40f3270
So i will drop this patch from the series and hope the firmware isn't
customized.
Best regards

Hi Arend,

my patch based on a similar patch [1] by Mikhail Rudenko. I falsely
assumed that the Ampak AP6212 and Raspberry Pi Zero 2 W are using
different wifi chips. But now it i think they are identical. If i grep
the firmware blob for the Raspberry Pi Zero 2 W, i getting this:
# strings firmware.bin | grep 4343
43436b0-roml/sdio-g-pool-p2p-pno-pktfilter-keepalive-aoe-mchan-proptxstatus-ampduhostreorder-lpc-wl11u-fmc-wepso-anqpo-srmem-srfast-11nprop-ob-ndoe-rssiindur-bcol-gtr-mfp-sdiorxenhance-extsae
Version: 9.88.4.65 (test) (f149b32@shgit) (r679549) CRC: 3e0bc4b6 Date:
Fri 2020-10-09 14:45:07 CST Ucode Ver: 1043.20742 FWID: 01-f40f3270
So i will drop this patch from the series and hope the firmware isn't
customized.
Best regards
