There are provedly different firmware variants for the different
phones using some of these chips. These were extracted from a few
Samsung phones:
37446 BCM4334B0.samsung,codina-tmo.hcd
37366 BCM4334B0.samsung,golden.hcd
37403 BCM4334B0.samsung,kyle.hcd
37366 BCM4334B0.samsung,skomer.hcd
This patch supports the above naming schedule with inserting
[.board_name] between the firmware name and ".hcd". This scheme
is the same as used by the companion BRCM wireless chips
as can be seen in
drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c
or just by looking at the firmwares in linux-firmware/brcm.
Currently we only support board variants using the device
tree compatible string as board type, but other schemes are
possible.
This makes it possible to successfully load a few unique
firmware variants for some Samsung phones.
