It boots. I have working network on the WAN port, both USB ports detect
a device when I plug one in.

Looking at platform devices without a driver, enabling the following
drivers might be beneficial:

	CONFIG_ARM_ARMADA_37XX_CPUFREQ 
	CONFIG_CRYPTO_DEV_SAFEXCEL
	CONFIG_ARMADA_37XX_RWTM_MBOX 
	CONFIG_ARM_ARCH_TIMER
	CONFIG_ARM_PSCI_CPUIDLE 
	CONFIG_ARM_PSCI_FW

Best regards
Uwe
