Hi, I have BCM63168 device with b43 driver, The WLAN chip BCM43217 doesn't get detected, I saw some devices in openwrt source that add "sprom fallback" and "fixups" for BCM43217,sprom fallback, sprom fallback 2.
In GPL release i have the file bcmdrivers\broadcom\net\wl\impl14\bcm4321_map.bin_save which is same as
static __initconst u16 bcm4321_sprom from sprom fallback 2.
What are sprom fallbacks, can it help me detect the BCM43217 chip? if so, how can I know the fixup values?
