Pretty much every SOC with programmable logic or FPGA boards have unlimited amount of configurations and make no sense to describe all of them. It means what make sense to describe are boards which people can look, check and compare that configuration against their custom design. But if there is no public documentation what you want to use to compare against? Can anybody even buy this board? (I expect you can buy that phones and laptops). Thanks, Michal
