ARM: zynq: Point via nvmem0 alias to eeprom on zc702/zc706

Browse Source 
EEPROM stores identification information about board like a board name,
revision, serial number and ethernet MAC address. U-Boot is capable to read
nvmemX aliases and read/display provided information when nvmem alias link
is described.
