[PATCH] bsp: use mainline/QCA driver and firmware for ath10k WiFi

Mo Mär 30 18:53:52 CEST 2020

Hallo Adrian,

für den mainline ath10k gab es doch auch mal irgendwo einen Patch, der die Buffer verkleinert, oder?
Ich kann ihn grade nicht mehr finden.

Ohne den sind 64MB RAM Geräte ziemlich sicher auch mit dem mainline ath10k kaputt.

Gruß
Fabian
