- * Search the device tree for the best MAC address to use. 'mac-address' is

- * 'address' is checked, just in case we're using an old device tree.
- *
- * Note that the 'address' property is supposed to contain a virtual address of
- * the register set, but some DTS files have redefined that property to be the
- * MAC address.
- *
- * All-zero MAC addresses are rejected, because those could be properties that
- * exist in the device tree, but were not set by U-Boot. For example, the
- * DTS could define 'mac-address' and 'local-mac-address', with zero MAC
- * addresses. Some older U-Boots only initialized 'local-mac-address'. In
- * this case, the real MAC is in 'local-mac-address', and 'mac-address' exists
- * but is all zeros.
