Cover letter [Buildroot] [PATCH v3 0/7] Add rpi3 b+ support

Hello Martin,

Quoted 21 lines · Thomas Petazzoni

Hello,
Quoted 4 lines · Martin Bark
The only reason for this seems to be the use of the pi3-miniuart-bt overlay. Personally i never use this overlay, I set enable_uart=1 in config.txt (the same as raspi-config does). Is there a reason buildroot favours the pi3-miniuart-bt overlay?
I am not familiar with those configuration details of the RPi platform, but I remember they have been discussed in the past. Perhaps you can check the commit log for some details about them.
Especially this commit log:
