Subject: [PATCH] board: amlogic: vim3: fix setup ethernet mac from efuse
Date: Tue, 12 Jan 2021 12:30:11 +0800 [thread overview]
Message-ID: <20210112043011.722605-1-art@khadas.com> (raw)
Fix reading built-in ethernet MAC address from efuse
NOTE: MAC is stored in ASCII format, 1bytes = 2characters by 0 offset
if mac from efuse not valid we use meson_generate_serial_ethaddr
NOTE: remake odroid-n2.c variant from Neil Armstrong <narmstrong@baylibre.com>
