Subject: [PATCH] ARM: defconfig: add unified config for RPi3 and RPi4
|
||
|
|
|
||
|
|
Provide a defconfig which allows us to boot Raspberrry Pi 4
|
||
|
|
and Raspberry Pi 3 Model B/B+
|
||
|
|
Instead of using the embedded DTB as done in RPi3 we use the
|
||
|
|
devicetree provided by the firmware.
