AM6442: AM64x and AM65x, eth0 doesn't come up at boot with static IP

Hi TI team,

On both AM64x EVM and AM65x EVM I've noticed if I assign a static IP address to eth0 (by changing /etc/network/interfaces and rebooting), eth0 does not assign the static IP at boot. The NIC remains un-configured, but can be fixed by issuing "ifdown eth0 && ifup eth0" twice (one time doesn't seem to do it).

See AM64x EVM console log below showing eth0 is down until I issue ifdown/ifup two times in a row:
