Subject: ARM: dts: imx6ul: Set macaddress location in ocotp
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e2ba87c745ca7e11793be57d9a397f01966efa5b;p=linux.git

ARM: dts: imx6ul: Set macaddress location in ocotp

If a bootloader does not configure the MAC address, devices come up with
a random MAC at the moment.

ocotp provides registers for storing the mac-address.
Configure those for i.MX6UL and i.MX6ULL allows net/core to retrieve it from
there.
