Subject: [PATCH v1 0/2] Add driver support for Eswin eic7700 SoC PCIe controller

From: Senchuan Zhang <zhangsenchuan@...incomputing.com>

     Support for the Eswin eic7700 PCIe driver control program has been
    added to the Linux kernel, which is part of the Eswin SoC family.

    Features:
     Implements support for the Eswin eic7700 SoC PCIe controller,
    It is a high-speed data transmission interface, which can
    enhance the speed and performance of computers,It can be used
    to connect different types of devices.

    Supported chips:
     Eswin eic7700 series SoC.

    Test:
     Tested this patch on the Sifive HiFive Premier P550 (which uses the
    EIC7700 SoC),The pcie driver controller operates normally through
    the nvme peripheral test.
