@ -1256,8 +1256,32 @@ Properties in the template node are inserted into the destination node if they
do not exist there. In the example above, `some-property` is added to each of
`spi-image` and `mmc-image`.
Note that template nodes are not removed from the binman description at present.
Note that template nodes are removed from the binman description after
processing and before binman builds the image descriptions.
The initial devicetree produced by the templating process is written to the
`u-boot.dtb.tmpl1` file. This can be useful to see what is going on if there is
a failure before the final `u-boot.dtb.out` file is written. A second
`u-boot.dtb.tmpl2` file is written when the templates themselves are removed.
Dealing with phandles
---------------------
Templates can contain phandles and these are copied to the destination node.
However this should be used with care, since if a template is instantiated twice
then the phandle will be copied twice, resulting in a devicetree with duplicate
phandles, i.e. the same phandle used by two different nodes. Binman detects this
situation and produces an error, for example::
Duplicate phandle 1 in nodes /binman/image/fit/images/atf/atf-bl31 and
/binman/image-2/fit/images/atf/atf-bl31
In this case an atf-bl31 node containing a phandle has been copied into two
different target nodes, resulting in the same phandle for each. See
testTemplatePhandleDup() for the test case.
The solution is typically to put the phandles in the corresponding target nodes
(one for each) and remove the phandle from the template.
