Linux OS Update with a New Boot Stack

Syntacore, a RISC-V IP and tools specialist, announces an update to the Linux OS software package for Syntacore platforms, featuring OpenSBI v1.7, U-Boot v2025.10 and the new miniboot first-stage bootloader.

This release introduces an updated bootflow for the Linux OS software package:

  1. miniboot v2026.04
    A first-stage bootloader built on top of the existing HAL, replacing the legacy sc-bl bootloader. It performs only the essential hardware initialization.
  2. OpenSBI v1.7
    A standard SBI bootloader based on a community-driven open-source implementation.
  3. U-Boot v2025.10
    A standard second-stage bootloader for the Linux kernel.

This change migrates the DTS files to the main Linux kernel repository, following the standard Linux approach. It keeps the DTS files in the kernel source tree, decoupling DTB updates from the first stage bootloader and making it easier to update hardware descriptions.

The update also adds L3 cluster support for the high-performance application-class SCR9 core and corresponding DTS descriptions in the Linux kernel.
