Subject: smegw01: Read the second MAC address
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ea99d227f95f6849d5523e8d327b1805bb828254;p=u-boot.git

smegw01: Read the second MAC address

Currently, only the first MAC address is read from the fuses.

The second MAC address is not read and Linux assigns a random one.

To prevent this behavior, read the second MAC address from the fuses
and store it into the eth1addr environment variable so that it
can be passed to Linux.
