from your board code This allows your board environment to co-exist with other board specific environments that might be enabled in your config. Also I want to encourage you to add your board to imx_v7_defconfig rather than adding your own config. I want to keep the number of configs small as the config files tend to bitrot quiet fast. > diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile > index d77a7b6..a6cda6e 100644 > --- a/arch/arm/dts/Makefile > +++ b/arch/arm/dts/Makefile > @@ -68,6 +68,7 @@ pbl-dtb-$(CONFIG_MACH_SOCFPGA_TERASIC_SOCKIT) += socfpga_cyclone5_sockit.dtb.o > pbl-dtb-$(CONFIG_MACH_SOLIDRUN_CUBOX) += dove-cubox-bb.dtb.o > pbl-dtb-$(CONFIG_MACH_SOLIDRUN_MICROSOM) += imx6dl-hummingboard.dtb.o imx6q-hummingboard.dtb.o imx6q-h100.dtb.o > pbl-dtb-$(CONFIG_MACH_TECHNEXION_WANDBOARD) += imx6q-wandboard.dtb.o imx6dl-wandboard.dtb.o > +pbl-dtb-$(CONFIG_MACH_TOLINO_VISION) += imx6sl-tolino-vision.dtb.o > pbl-dtb-$(CONFIG_MACH_TORADEX_COLIBRI_T20) += tegra20-colibri-iris.dtb.o > pbl-dtb-$(CONFIG_MACH_TOSHIBA_AC100) += tegra20-paz00.dtb.o > pbl-dtb-$(CONFIG_MACH_TQMA53) += imx53-mba53.dtb.o > diff --git a/arch/arm/dts/imx6sl-tolino-vision.dts b/arch/arm/dts/imx6sl-tolino-vision.dts > new file mode 100644 > index 0000000..9c8c0fe > --- /dev/null > +++ b/arch/arm/dts/imx6sl-tolino-vision.dts > @@ -0,0 +1,225 @@ > +/* > + * Copyright (C) 2013 Freescale Semiconductor, Inc.

It's overwritten anyway by the real amount of SDRAM. Hardcoding it is a bit dangerous, because if the real amount of SDRAM is different from what hardcoded here you will get conflicts during RAM registration during barebox startup. > + > + leds { > + compatible = "gpio-leds";
