X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=ba74bcf3e07b;p=u-boot.git

xilinx: common: Remove zynq_board_read_rom_ethaddr()

Removing the zynq_board_read_rom_ethaddr() function as
xlnx,eeprom is not used anymore. As all board dts to use
nvmem alias instead of xlnx,eeprom.
