We have serveral projects for different cusomters, but may use the same
soc chip (different boards). Customer have different requriements. For
some customer focus on A2DP SINK role, they need a high throughput PKI of
BTC, then firmware requires more optimizaiton for coexistence when acting
as SINK role. While other projects only act as A2DP Source, they need the
optimizaiton for coexistence when acting as SRC role For basic Bluetooth
functions, they are included, but we can't included all the feature in a
signle firmware.
For PC projects, the focus is on A2DP SRC and HFP AG roles. Meanwhile,
for IoT projects, the focus is on A2DP SINK and HFP Client roles.

It's intended to separate the firmware from the IoT product and the existing product.
