help
barebox supports being configured from devicetree. This enables
support for this feature. This currently allows to configure the
environment path from devicetree and to partition devices. See
Documentation/devicetree/bindings/barebox/ for more information.

bool "Allow environment to come from file"
help
Allow the devie tree configuration of the barebox environment path
to specify a file in filesystem, which will be mounted.
config OF_OVERLAY
select OFTREE
bool "Devicetree overlays"
help
Overlays allow to patch the devicetree. Unlike Linux, Barebox does
not patch the live devicetree, but applies the overlays as fixup to
the devicetree. Furthermore, overlays cannot be removed after they
have been applied.
config OF_OVERLAY_LIVE
depends on OF_OVERLAY
bool "Support devicetree overlays on live devicetree"
help
This option allows to use devicetree overlays with the live
devicetree. It is not required to apply overlays to any other
devicetree.
This builds the build-in devicetree with __symbols__, which
significantly increases the size of the dtb file.
Enable this option only if you actually need the live devicetree
while applying in the devicetree overlay. This is usually the case if
applying the overlay has other side effects than changing the
devicetree.
