commit 22970070e027cbbb9b2878f8f7c31d0d7f29e94d upstream. Add alias for FEC ethernet on i.MX25, i.MX27, i.MX51 and i.MX53 to allow bootloaders (like U-Boot) patch-in the MAC address for FEC using this alias.

Without MAC address, the ethernet cannot be brought up and this makes such board unusable when booting from NFS. This patch lets the bootloader pass the MAC address via DT to the kernel properly, thus letting me boot from NFS again. diff --git a/arch/arm/boot/dts/imx25.dtsi b/arch/arm/boot/dts/imx25.dtsi index 737ed5d..de16119 100644 --- a/arch/arm/boot/dts/imx25.dtsi +++ b/arch/arm/boot/dts/imx25.dtsi @@ -30,6 +30,7 @@ spi2 = &spi3; usb0 = &usbotg; usb1 = &usbhost1; + ethernet0 = &fec; }; cpus { diff --git a/arch/arm/boot/dts/imx27.dtsi b/arch/arm/boot/dts/imx27.dtsi index 826231e..da2eb7f 100644 --- a/arch/arm/boot/dts/imx27.dtsi +++ b/arch/arm/boot/dts/imx27.dtsi @@ -30,6 +30,7 @@ spi0 = &cspi1; spi1 = &cspi2; spi2 = &cspi3; + ethernet0 = &fec; }; aitc: aitc-interrupt-controller@e0000000 { diff --git a/arch/arm/boot/dts/imx51.dtsi b/arch/arm/boot/dts/imx51.dtsi index 4bcdd3a..e1b6015 100644 --- a/arch/arm/boot/dts/imx51.dtsi +++ b/arch/arm/boot/dts/imx51.dtsi @@ -27,6 +27,7 @@ spi0 = &ecspi1; spi1 = &ecspi2; spi2 = &cspi; + ethernet0 = &fec; }; tzic: tz-interrupt-controller@e0000000 { diff --git a/arch/arm/boot/dts/imx53.dtsi b/arch/arm/boot/dts/imx53.dtsi index 7abe6c4..86df3f5 100644 --- a/arch/arm/boot/dts/imx53.dtsi +++ b/arch/arm/boot/dts/imx53.dtsi @@ -34,6 +34,7 @@ spi0 = &ecspi1; spi1 = &ecspi2; spi2 = &cspi; + ethernet0 = &fec; }; cpus { -- 2.0.1 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
