[RFC PATCH 2/7] dtc: add -@ option to enable __symbols__

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The devicetree overlay driver requires the __symbols__ node to resolve
phandles to the base devicetree. As Barebox applies the overlay to the
live devicetree, the build-in devicetree must be built with the
__symbols__ node.
