Hello list, My board is Marvell Armada 3720 Espressobin variant I am trying to upgrade from uboot v2017 to latest one I was able to get to uboot shell prompt after disabling almost all and leaving only network. For a network board has Marvell switch. I added some debug prints to drivers/phy/marvell/comphy_a3700.c
