This usually happens, mantainers could decide to split one kernel driver
into two or more to make maintenance easier. Is something like b43
legacy drivers from broadcom and b43 standard.
In the future probably you will see this again with a driver splitted to
support arrow lake or whatever intel "code name" that arrives.
This has happened to me recently, with a rockpi4c+. The rock pi 4c+
brings one realtek 8211T that "should be" supported by Realtek_phy
(CONFIG_REALTEK_PHY) but not. I had also to enable CONFIG_STMMAC_ETH to
make it works enabling also STMicroelectronics net adapter :-/
So, a lot of times you will find surprises as this, So test error and
recompile (in a rock pi 4c+ it takes around 8 hours a full compilation)
Now I'm trying to enable the broadcom 43455 sdio that its shipped with
it (the cause is the damned dtb or lack of support of the correct kernel
option, (I already actived CONFIG_B43_SDIO and BRCMFMAC_SDIO....) or
firmware, what will be... will be....)
