I suppose you are right. I would be surprised if the firmware images
were the same for sdio, usb and pci. Hopefully all sdio chipsets sharing
the same device id and BMI version will use the same firmware image.
Currently, these two params are the only two that are used when
selecting firmware.

struct bmi_target_info also has a type parameter, but I can't see it
being used anywhere in the code.

If it turns out that several sdio chipsets uses the same BMI version and
device id, this parameter might be used (together with the other two) to
select hw params.
