  Introduce a driver for the Eswin eic7700 series SoC ethernet controller,
  adding support for the ethernet functionality in the Linux kernel. The
  driver provides basic functionality to manage and control the ethernet
  signals for the eic7700 series chips, which are part of the Eswin SoC family.

  Supported chips:
    Eswin eic7700 series SoC.

  Test:
    I tested this patch on the Sifive HiFive Premier P550 (which uses the EIC7700 SoC),
    including system boot and ethernet.
