It also features various interfaces such as DDR4, Gbit-Ether, CAN, USB 3.2, SD/MMC, etc., making it ideal for high-performance computing scenarios. This patch series introduces initial SoC DTSI support for the StarFive JH8100 SoC. The relevant dt-binding documentation has been updated accordingly. Below is the list of IP blocks added in the initial SoC DTSI, which can be used for booting via initramfs on FPGA: - StarFive Dubhe-80 CPU - StarFive Dubhe-90 CPU - PLIC - CLINT - UART The primary goal is to include foundational patches so that additional drivers can be built on top of this framework. Changes since v1: - Dropped patch 5. - Moved timebase-frequency from .dts to .dtsi. - Moved soc node from .dts to .dtsi. - Revised the title for the dt-binding document by removing Xilinx wording. - Added a full stop to the end of the commit messages. - Removed extra blank lines. - Used hyphen for a node name. - Added more recipients to the mailing list.
