This can be verified by reading the value of the AHB1_APB1_CFG_REG register via /dev/mem. It always reads as 0x3180 regardless of the current cpufreq operating point. So this configuration should be safe for use in U-Boot too. PLL6 also needs to be configured before it is used as the clock source, according to the "CCU / Programming Guidelines" section of the Allwinner manual. The current low AHB1 clock speed is limiting the USB transfer speed when booting via FEL. This patch can increase the FEL USB transfer speed from ~510 KB/s to ~950 KB/s.

As such the board comes with a built-in switch chip giving it 5 gigabit ethernet ports, and it has a large empty area on the pcb with mounting holes which will fit a 2.5 inch harddisk. To complete its networking features it has a Realtek RTL8192CU for WiFi 802.11 b/g/n. The dts file is identical to the one submitted upstream.
