Want to realize 1588 Solution，Which boards can support this solution?

If you refer to the an739, it uses the Arria V SoC, where the software stack is running on Soc. The Arria V GX device does not have the SoC, if your custom board has external SoC or processor then you may consider implementing the software stack over there if possible
