Subject: [PATCH] rpi: Use firmware provided device tree
|
|
|
|
Currently the firmware generates a device tree for us that we could
|
|
just use to adjust ourselves. We then on boot throw that away and
|
|
use our own built-in device tree to configure device access.
|
|
|
|
This is bad for a multitude of reasons. For starters, it breaks
|
|
overlay support in config.txt, confusing users. Much worse however
|
|
is that we are stuck with individual U-Boot builds per board.
|
|
The firmware can easily give us the right DT depending on the
|
|
target board and revision though.
|
|
|
|
So let's use the firmware provided device tree instead. That way
|
|
U-Boot as well as payloads loaded by it can automatically adapt
|
|
to variants of RPi hardware.
