At TPL (bootph-pre-sram) or SPL (bootph-pre-ram) phase 2. At U-Boot proper pre-relocation phase 3. At U-Boot proper normal phase However the binding and U-Boot Driver Model documentation indicate that only nodes marked with bootph-all or bootph-some-ram should be bound in the U-Boot proper pre-relocation phase. Change ofnode_pre_reloc to report a node with bootph-pre-ram/sram prop with a pre-reloc status only after U-Boot proper pre-relocation phase. Also update the ofnode_pre_reloc documentation to closer reflect the binding and driver model documentation. This changes behavior of what nodes are bound in the U-Boot proper pre-relocation phase. Change to bootph-all or add bootph-some-ram prop to restore prior behavior.
