76  * Search the device tree for the best MAC address to use.  'mac-address' is
77  * checked first, because that is supposed to contain to "most recent" MAC
78  * address. If that isn't set, then 'local-mac-address' is checked next,
79  * because that is the default address. If that isn't set, then the obsolete
80  * 'address' is checked, just in case we're using an old device tree. If any
81  * of the above isn't set, then try to get MAC address from nvmem cell named
82  * 'mac-address'.
84  * Note that the 'address' property is supposed to contain a virtual address of
86  * MAC address.
88  * All-zero MAC addresses are rejected, because those could be properties that
89  * exist in the device tree, but were not set by U-Boot.  For example, the
90  * DTS could define 'mac-address' and 'local-mac-address', with zero MAC
91  * addresses.  Some older U-Boots only initialized 'local-mac-address'.  In
92  * this case, the real MAC is in 'local-mac-address', and 'mac-address' exists
