From d7fee7d8991e7f0eafd59e3389ec9162d540438a Mon Sep 17 00:00:00 2001 From: Alistair Delva Date: Mon, 29 Mar 2021 16:11:39 -0700 Subject: [PATCH] ANDROID: Disable BT UART on rockpi4. Enabling the BT UART seems to break boot. Corruption can be seen on the serial UART (uart2) just before the device restarts. As we aren't using this device anyway, disable it until we have time to diagnose it.
