The DE4 board was the first board they used with doing the compiler in 2012-13. If you look in hdl/ip you will see all the built-in functions that are used by the compiler. These ip may call out megawizards for use by the compiler. Supporting a device family is a lot of work so they don't support the S4 anymore. The s5_ref is a board that had lots of resources so they use that board as a reference as you can rip out what your board does not use. Mainly when porting you have to get the memories and PCIe pin numbers correct and then do a good layout and keep floating out of the center. The s5_ref has PCIe, DDR3. There is a s5_net that also has QDRII, and channels for ethernet connections. If you are just looking for a board to learn OpenCL on try a c5soc board. They're fun!
