Could you please elaborate, what new features are needed for this as you
add common functions?
Please document the datasheet.

Could you please elaborate, what new features are needed for this as you add common functions?
Please document the datasheet.
[Tim] no new feature, only support new chip qca2066 btfw downloading

The coding style requires { } around branches, once it’s used in any branch.

As I wrote, you add common functions like `qca_read_fw_board_id()`,
which were not required before. So please elaborate in the commit message.
