Subject: board: amlogic: add meson_generate_serial_ethaddr fallback to p200
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=65d5c367b00cb392bda560c3da1834979adcf137;p=u-boot.git

board: amlogic: add meson_generate_serial_ethaddr fallback to p200

Add a fall-back method to generate ethaddr from CPU serial on p200 boards
if the MAC cannot be read from efuse. This prevents random MAC addresses
on the WeTek Hub/Play2 boards.
