The preferred way is to create a new dtsi file with the U-Boot specific additions. This will get included automatically in the build process. Please see this file for example: arch/arm/dts/mt7622-u-boot.dtsi This will also enable us to stay in sync with the Linux DT files. > resetctl-reboot { > compatible = "resetctl-reboot"; > > resets = <&rstctrl MT7628_SYS_RST>; > reset-names = "sysreset"; > + u-boot,dm-pre-reloc; > }; > > clkctrl: clkctrl at 0x2c { > @@ -42,6 +45,7 @@ > reg = <0x34 0x4>; > compatible = "mediatek,mtmips-reset"; > #reset-cells = <1>; > + u-boot,dm-pre-reloc; > }; > > pinctrl: pinctrl at 60 { > @@ -52,6 +56,8 @@ > pinctrl-names = "default"; > pinctrl-0 = <&state_default>; > > + u-boot,dm-pre-reloc; > + > state_default: pin_state { > }; > > @@ -260,6 +266,8 @@ > reset-names = "uart0"; > > reg-shift = <2>; > + > + u-boot,dm-pre-reloc; > }; > > uart1: uart1 at d00 { > @@ -275,6 +283,8 @@ > reset-names = "uart1"; > > reg-shift = <2>; > + > + u-boot,dm-pre-reloc; > }; > > uart2: uart2 at e00 { > @@ -290,6 +300,8 @@ > reset-names = "uart2"; > > reg-shift = <2>; > + > + u-boot,dm-pre-reloc; > }; > }; > > Viele Grüße, Stefan

To enable DM support in SPL, some necessary nodes must be reserved for serial, clk, sysreset and other drivers. This patch adds u-boot,dm-pre-reloc for these nodes.
