From: Patrick Oppenlander <patrick.oppenlander@gmail.com> This is duplicated from the U-Boot makefile & Kconfig. Similarly to U-Boot custom boards sometimes need to adjust the U-Boot devicetree. For example, the AM64x SDRAM controller supports inline ECC which needs to be enabled in the R5 loader devicetree. Please note that some versions of U-Boot have broken external devicetree support and may require manual patching to build. See commit 3609e1dc5f4d4c238dcd23e045ba6223310feffa in the U-Boot tree.
