Note:
    1, disable BTRFS(will trigger a link error with *some* RV64 GCC)
    But RV64 GCC on Fedora works well with enabling BTRFS.

    BTRFS will select ZSTD which will trigger a link error with
    *some* RV64 GCC:

    2, enable OF_SEPARATE:
    This is required so that openSBI can add itself to /reserved-memory, and
    let EFI know about it.

    3, Set default fdtfile name
