This worked in the sense that I could flash the trust zone firmware and U-Boot, and net-next will boot without hanging, but now the board is in a boot loop, due to what appears to be watchdog timer expiration. This happens regardless of whether CONFIG_ARMADA_37XX_WATCHDOG is set to y or n in the booted kernel.
