2021-02-04Add support for Realtek RTL838x/RTL839x switch SoCsBert Vermeulen
The RTL838x/839x family of SoCs are Realtek switches with an embedded MIPS core. * RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features * RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 features These switches, depending on the exact part number, will have anywhere between 8 and 52 ports. The MIPS core is wired to a switch cpu port which has a tagging feature allowing us to make use of the DSA subsystem. The SoCs are somewhat basic in certain areas, getting better with more advanced features on newer series. The switch functionality is MMIO-mapped via a large MFD region. The SoCs have the following peripherals * ethernet * switch * uart - ns16550a * spi-flash interface * gpio * wdt * led The code was derived from various vendor SDKs based on Linux v2.6 kernels. This patchset allows us to boot RTL838x/RTL839x units with basic support. Most of the other drivers are already written and functional, and work to get them upstream is already in progress.
