The AP6359SA is a BCM4359 SDIO-based Wi-Fi/Bluetooth module that PINE64
sells specifically for the ROCKPro64 device. This commit starts a
firmware package to support it specifically, while others can later add
firmware for other modules sold for the device. Also add this package as
a nonfree subpackage dependency in the ROCKPro64 device APKBUILD.
I was unable to find a suitable license for the firmware blobs, so until
we find a suitable repository containing all of the required files by
the module with a license included, or contact the vendor directly,
let's use LibreELEC's repository without a license for now.
