-You can do step-4 manually with
-.. code-block:: console
- $ dtc -@ -I dts -O dtb -o signature.dtbo signature.dts
- $ fdtoverlay -i orig.dtb -o new.dtb -v signature.dtbo
-where signature.dts looks like::
- &{/} {
signature {capsule-key = /incbin/("CRT.esl");};- };
+You can perform step-4 by defining the Kconfig symbol +CONFIG_EFI_CAPSULE_ESL_FILE. This symbol defines the path to the esl +file generated in step-2. Once the symbol has been populated with the +path to the esl file, the esl file will automatically get embedded +into the platform's dtb as part of u-boot build.
Executing the boot manager
-- 2.34.1
This should be handled as part of the binman build.
