This is intended for bare metal platforms. The DTB binary can be embedded in the firmware image by adding the following to the platform .fdf file: FILE FREEFORM =3D 25462CDA-221F-47DF-AC1D-259CFAA4E326 { SECTION RAW =3D SomePkg/path/to/foo.dtb } Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel --- This depends on patch 4/12 of Laszlo's series https://lists.01.org/pipermail/edk2-devel/2017-March/009004.html Note to Marcin: the setup page was only tested with the generic BDS, not the Intel BDS. This shouldn't matter in practice, since they should both implement the prerequisite protocols, but moving to the generic BDS is probably a good idea regardless.
