    platform/xilinx: replace PLLs with DCMs on Spartan-6 · 21c67bc8
    Dimitris Lampridis authored
    Every clock management block in Spartan-6 has 2xDCM and 1xPLL. PLLs are therefore a scarcer resource
    and should be preserved for user applications whenever possible. In this case, it is very much possible
    to generate the necessary clocks via DCMs. Furthermore, we expose the unused CLKFX output of one of the
    DCMs (along with a generic to configure the multiplication/division factors), in case it can be used
    by the user application.
