Just a few questions/remarks.

> +ATSAME54P20A SoC. The SoC includes a SAME54 ARM Cortex-M4F microcontroller.
+For programming the MCU comes with 256Kb of RAM and 1024Kb of flash memory.
+
+The same54-xpro is available from various hardware vendors for ~70USD (as of
+2019 March).

+## Flashing the device
+
+Connect the device to your Micro-USB cable using the port labeled as *DEBUG
+USB*.
+
+The standard method for flashing RIOT to the same54-xpro is using OpenOCD.

I'm not against using openOCD but EDBG is usually faster to flash. Could you also add it ?
Selection should be done by the user using PROGRAMMER=edbg or PROGRAMMER=openocd in a Makefile.
