To achieve this, device tree compatible string was used as boardname and
the value of it will be checked against supported_devices list.
It should be noted that we do not distinguish between
sun5i-a13-olimex-som and sun5i-a13-olinuxino as they share the same dts
file.
The other thing is that we need to gunzip the generated firmware to do
fwtool check.
