We can remove the pre reloc property in SPL and TPL device-tree: - u-boot,dm-pre-reloc - u-boot,dm-spl - u-boot,dm-tpl As only the needed node are kept by fdtgrep (1st pass). The associated function (XXX_pre_reloc) are simple for SPL/TPL: return always true. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
