[ELDK] [PATCH 10/10] META-ELDK: linux-eldk: Backport bugfix for reading FEC MAC from DT

[Marek Vasut]

Backport a patch from mainline Linux which allows the U-Boot bootloader
(or any other bootloader) pass the MAC address for the FEC ethernet via
DT aliases. This fixes a problem where the FEC had a random MAC address
in Linux instead of proper one passed from U-Boot.

+Subject: [PATCH] ARM: dts: imx: Add alias for ethernet controller
+
+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.
