Kernel Device Tree support is now easier to enable in a kernel
recipe.
The Device Tree code has moved to a
kernel-devicetree
class.
Functionality is automatically enabled for any recipe that inherits
the
kernel
class and sets the
KERNEL_DEVICETREE
variable.
The previous mechanism for doing this,
meta/recipes-kernel/linux/linux-dtb.inc
,
is still available to avoid breakage, but triggers a
deprecation warning.
Future releases of the Yocto Project will remove
meta/recipes-kernel/linux/linux-dtb.inc
.
It is advisable to remove any require
statements that request
meta/recipes-kernel/linux/linux-dtb.inc
from any custom kernel recipes you might have.
This will avoid breakage in post 2.4 releases.
