+------------------------------
+* u-boot may fail to read MAC addresses from EEPROM on some boards and there
+  won't be MAC addresses set in environment. This may cause kernel fails to
+  probe these network interfaces. The workaround is to set MAC addresses
+  manually, for example,

+  => setenv ethaddr 00:04:9F:04:65:4b
+  => setenv eth1addr 00:04:9F:04:65:4c
