X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=ce92321559dbc66434c9d07ec338a72c4dc159c3;p=u-boot.git

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

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.
