e29db6724c sched,fs,docs: support setuid sudo helper
Supports the UNIX setuid-on-exec sudo helper. Documents the model,
generates an extra ROMFS user and /etc/sudoers for a non-root test,
reports BINFS modes from the builtin table so ls -l matches execute
bits, and skips NULL environment entries when sanitizing a setuid exec.

4761f15b3e !tools/mkpasswd: PBKDF2 host tool and ROMFS passwd build integration
Add standalone host PBKDF2-HMAC-SHA256 mkpasswd, board_romfs_mkpasswd.sh,

ab6b1fd6f9 !build: add build-time password generation with mkpasswd tool.
Introduce mkpasswd, a pure-C host tool for generating encrypted password
files at build time using TEA encryption. This enables secure,
credential-free firmware images while allowing build-time password
configuration.

Changes:
* Add mkpasswd.c host tool for TEA-based password hashing and encryption
* Integrate mkpasswd into Make build system (tools/Makefile.host)
* Add CMake support for mkpasswd compilation and ROMFS passwd generation
* Add CONFIG_BOARD_ETC_ROMFS_PASSWD_* configuration options to Kconfig
* Implement credential exclusion from defconfig to prevent password leaking
* Update savedefconfig.cmake to strip sensitive credentials
* Fix mkdir() portability for Windows Native builds (CONFIG_WINDOWS_NATIVE)
* Change default username from "admin" to "root" (POSIX convention)
* Improve build-failure error message with full menuconfig navigation path

BREAKING CHANGE: Boards enabling CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE
must set CONFIG_BOARD_ETC_ROMFS_PASSWD_PASSWORD to a non-empty string
of at least 8 characters. The build now fails with an explicit error if
this config is left empty. To fix: run 'make menuconfig' and navigate to:
  Board Selection --->
    Auto-generate /etc/passwd at build time --->
      Admin password

e9e9c76a76 cmake(enhance):include-style defconfig can modified via menuconfig
1. enhanced process_config.py script: supports both preprocess and postprocess modes

2. in preprocess mode: handles include formats and recursively records the include config tree structure to prepare for postprocess

3. In postprocess mode: compares the original file with menuconfig to identify non-#include items that should be written back

4. olddefconfig stores the original compressed include defconfig file at the very beginning

5. savedefconfig saves both the original file and the written back include defconfig

cd46d27489 cmake:Remove Unix-specific code and replace it with cmake script to support cross-platform
the Unix-specific commands used in the CMake implementation of savedefconfig are not
supported on the Windows platform, which will cause compatibility issues.

replace it with CMake implementation, which can be cross-platform and has been verified on Windows.
