Subject: xilinx: Move zynq_board_read_rom_ethaddr to shared location
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9755e3db8b1223699954146dfb171df75ec89ab3;p=u-boot.git

xilinx: Move zynq_board_read_rom_ethaddr to shared location

Zynq and ZynqMP are sharing similar code and there is no reason to do
code duplication. Move zynq_board_read_rom_ethaddr() to common file for
easier conversion to DM.
Use ZynqMP version that's why also add CONFIG_ZYNQ_EEPROM_BUS to Syzygy
which is only one Zynq board which is using this feature.
