For now it is true that they are used only on one board with an iMX.51 but this is not a strong dependency and it might change in the future if Technologic Systems decide to reuse these IPs on boards based on different SoCs. As the FPGA and the SoC are two separate chips, I don't know how such dependency should be expressed in kconfig. Thanks, Damien
