How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.

The system can boot normally and all other functions work fine, including PCIe support, but the WiFi and Bluetooth functionalities are not available due to the lack of corresponding drivers for AP6236 in the Armbian/firmware.I have submitted the corresponding driver for AP6236 to Armbian/firmware. Please kindly review and accept it.
