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

[Marek Vasut]

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.

NOTE: Without this backport, the ethernet adapter on most of the boards
      with the i.MX CPUs does not know it's MAC address (the controller
      does not have an EEPROM). 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.

Since the patch is already on mainline, and the submitting target is
3.14.x stable kernel, you should really send it to Greg.

No, Marek did the right thing here by sending it to the stable at vger
mailing list, never send stable patches only to me.

So this is not enough to add this "# 3.14.x" ? I followed the stable submissing 
guidelines, but I probably missed something then ?

Whew, I was really worried I messed the submission up. Thank you for confirming 
this is the right way to do it.

If I cannot even properly boot from an NFS root with v3.14.y , it seems to me to 
be problem enough. Also, MAC address should be a unique identifier, if the FEC 
picks a random MAC, it will wreak havoc on the network (in the better case).

I agree this is not a good thing.  But it's neither a regression nor a
critical issue as defined by stable_kernel_rules.txt.

Without this patch, you will not get a mac address patched into the DT by the 
bootloader. Therefore, your device will use a random mac address on the network 
which is different on every boot. This is not a good thing, don't you agree?

I do not see why this is a stable material.  But you do not need my
approval to send patch for stable kernel.  The person you need to
convince is Greg.

Add alias for FEC ethernet on i.MX to allow bootloaders (like U-Boot)
patch-in the MAC address for FEC using this alias.
