sim: Add Berry interpreter configuration.
Add a sim:berry configuration for the optional Berry scripting
interpreter and document its command and dependencies.
Use the current simulator NXInit startup path rather than nsh_main
so init.rc runs correctly. Enable BINFS for the built-in shell and
child status support for NXInit. Remove FSUTILS_PASSWD settings whose
dependencies are disabled, keeping the defconfig normalized against
current nuttx-apps.
The resulting source tree is identical to the previously tested
two-commit PR head; this commit squashes the initial addition and
the follow-up configuration fix at the maintainer's request.
Testing (Ubuntu 24.04 x86_64, GCC 13.3.0):
- Two consecutive refresh.sh --silent sim:berry runs passed without
tracked defconfig changes.
- Clean make -j1 and make -j8 builds passed.
- The simulator started cleanly, mounted /bin, /etc, /proc and /tmp,
and cleanly powered off.
- Berry 1.1.0 printed 42 for berry -e print(40+2);
file write/read smoke tests on /tmp passed.
- git diff --check and source-file checkpatch passed.
- The separately identified apps untracked Berry archive/source CI
failure is addressed by companion nuttx-apps branch
speccy88:fix/berry-ci-gitignore, pending upstream merge.

+==================================
+``berry`` Berry scripting language
+==================================
+
+Berry is a small embedded scripting language implemented in ANSI C99. The
+``berry`` command provides a compiler, register-based virtual machine, garbage
+collector, file I/O, bytecode loading and saving, and built-in modules for
+small on-device scripts.
+
+Configuration
+=============
+
+Enable Berry with ``CONFIG_INTERPRETERS_BERRY``. The interpreter is built as
an
+NSH built-in command with the following options:
+
+``CONFIG_INTERPRETERS_BERRY_PROGNAME``
+ Command name used to start Berry. The default is ``berry``.
+
+``CONFIG_INTERPRETERS_BERRY_PRIORITY``
+ Task priority for the interpreter. The default is ``100``.
+
+``CONFIG_INTERPRETERS_BERRY_STACKSIZE``
+ Stack size for the interpreter task. The default is ``12288`` bytes.
+
+Berry depends on ``CONFIG_ARCH_SETJMP_H``, ``CONFIG_LIBC_FLOATINGPOINT``, and
+``CONFIG_SYSTEM_SYSTEM``. The default NuttX Berry configuration enables the
+file, JSON, math, time, OS, GC, debug, strict, introspection, and bytecode
+modules. Shared-library module loading is disabled, so Berry does not require
+``CONFIG_LIBC_DLFCN``.
+
+The math module requires a math library. Use the NuttX ``LIBM`` config or a
+toolchain-provided math library.
+
+Usage
+=====
+
+Run a script from any mounted filesystem:
+
+.. code-block:: console
+
+ nsh> berry hello.be
+ nsh> berry /scripts/blink.be
+
+Run inline source:
+
+.. code-block:: console
+
+ nsh> berry -e print(40+2)
+ 42
+
+Start the interactive prompt:
+
+.. code-block:: console
+
+ nsh> berry
+ Berry 1.1.0 (build in Jun 26 2026, 09:07:01)
+ [GCC 13.2.0] on NuttX (default)
