Summary

  • This PR contains the following 2 commits.
    • commit1: arch: risc-v: Assign dedicated virtual addresses for text and heap
      • Current RISC-V/NuttX implementation assumes that text/data/heap
        areas are continuous. In fact, CONFIG_ARCH_TEXT_VBASE and
        CONFIG_ARCH_HEAP_VBASE are not used for memory allocation.
      • This commit assigns dedicated virtual addresses for text and heap
        which are the same approach to ARM-v7A/NuttX implementation.
    • commit2: boards: rv-virt: Assign dedicated text/heap area in knsh64/defconfig
      • This commit assigns dedicated text/heap areas that improve
        stability issues with rv-virt:knsh64

Impact

  • None

Testing

  • Tested with qemu-6.2
