Default to 'board.bin' for the legacy board data file, in case the
hw_params array doesn't list hw-specific board data file name (e.g. for
WCN3990).

Could you provide more background _why_ this is needed. What are you
trying to fix?

Sure. For wcn3990 we do not have the
`ath10k_hw_params_list[].fw.board' set. So if the board data is not
present in `board-2.bin', the driver will skip looking into
`board.bin' and will error out.
I had two options: either to set the `.fw.board' in
`ath10k_hw_params_list', or to provide this default. Granted that the
check for `fw.board' also prevents the `board-%s-%s.bin' lookup, I
opted for the second option.
Maybe I should just set the .fw.board to "board.bin" and
.fw.board_size to 26328 (?)

Ah, now I understand.

Yeah, I think that would be much better to set those fields for WCN3990.
Please also include to the commit message the description you wrote
above.
I can't remember anymore why even have this struct
ath10k_hw_params_fw::board field in the first, most likely due to some
legacy reasons before we had board-2.bin. I suspect all the fields even
contain the same "board.bin" string so in theory the field is not really
needed.
