If a node request a new node or it's parent node. the request's node will probe a double time.
So we check the device object of node in ofw probe entry and ofw probe child exit.

This commit introduces a page poison debugging mechanism and additional
assertions for memory management, improving system maintainability and
debugging capabilities. The changes aim to detect illegal memory usage
early and provide better clarity in managing page allocations.
Changes:
- Added `RT_DEBUGGING_PAGE_POISON` option to enable memory usage tracing.
- Introduced a page poisoner for detecting illegal memory usage.
- Implemented region-based memory tracking using bitmaps.
- Enhanced spinlock protection for memory management operations.
- Fixed several assertion checks for memory safety.
- Renamed macros for consistency (`FLOOR` to `CEIL`).
- Refined memory allocation and deallocation logic to include poisoning.
- Updated Kconfig to add configurable `RT_PAGE_MAX_ORDER` and poison debugging.
- Improved debugging outputs for page regions and memory operations.

This patch refactors the `rt_page_install` function by delegating specific
operations to new helper functions. Besides, the contiguous page regions
are now separated to segments of fixed size. The goal is to improve the
overall code readability, enhance modularity, and ensure better handling
of page installation logic through clearer separation of concerns.
Changes:
- Introduced `_get_mpr_ready_n_install` to encapsulate memory preparation
and page installation logic.
- Added `_update_region_list` for updating the installed page registry.
- Defined `_PAGE_STRIPE` for optimized region processing.
- Modified `rt_page_install` to handle regions in smaller chunks using
helper functions for better maintainability.
- Improved locking mechanisms with `rt_spin_lock` for thread safety.
- Reduced code duplication and clarified shadow region calculations.

This patch introduces a tagged pages allocator to address the existing problems
of page aliasing on specific platforms and the requirement of page coloring.
It implements an affinity-id aware page manager by separating the runtime page
list into two types: a normal single linked-list and a multi-dimensional affinity-list.
Changes:
- Introduced tagged pages allocator and managing algorithm for affinity pages list
- Modified components to support affinity-id list management
- Updated page allocation and freeing functions to handle tagged pages
- Added configuration options for page affinity block size and debugging
- Modified mmap and elf loading to respect affinity settings
- Enhanced page list management to support multi-dimensional affinity-list

[Problem Description]
1. When enabling RT_USING_MODULE=y, compilation warnings occur:
dlelf.c:386:27: warning: cast from pointer to integer of different size
dlelf.c:398:25: warning: cast from pointer to integer of different size
dlelf.c:408:24: warning: cast from pointer to integer of different size
2. On RV64 architectures (e.g. Sophgo SG2042 with RISC-V Sv39 and 40-bit physical addressing),
dlsym may fail when accessing addresses beyond 32-bit range.
[Root Cause]
In dlmodule_load_relocated_object() and dlmodule_symbol_find(),
pointer is cast to rt_uint32_t which truncates:
| rt_ubase_t rodata_addr = (rt_uint32_t)ptr;
This causes:
- Warnings on 64-bit systems (pointer width > 32-bit)
- Actual address truncation on RV64 when physical address exceeds 32-bit
[Solution]
Replace rt_uint32_t with architecture-adaptive rt_ubase_t:
| rt_ubase_t rodata_addr = (rt_ubase_t)ptr;
The rt_ubase_t is defined in include/rttypes.h as:
| #ifdef ARCH_CPU_64BIT
| typedef rt_uint64_t rt_ubase_t;
| #else
| typedef rt_uint32_t rt_ubase_t;
| #endif
This ensures correct width casting for both 32/64-bit architectures.

[Problem Description]
When assigning name to rt_object, strncpy() uses size equal to RT_NAME_MAX,
which causes missing null-terminator and overflows into adjacent 'type' field.
This corruption leads to unexpected system behavior.
[Problem Analysis]
The rt_object structure defines:
| char name[RT_NAME_MAX] | -> buffer
| rt_uint8_t type | -> adjacent field
Original code calculates size as:
size = end - first + 1;
if (size > RT_NAME_MAX) size = RT_NAME_MAX;
When size equals RT_NAME_MAX, strncpy() will copy exactly RT_NAME_MAX bytes
without adding terminating '\0', causing two issues:
1. name buffer is not null-terminated
2. The implicit null-byte writes beyond name[] into type field
[Solution]
Change boundary check from:
if (size > RT_NAME_MAX) size = RT_NAME_MAX;
to:
if (size >= RT_NAME_MAX) size = RT_NAME_MAX - 1;
This ensures:
1. Always leaves space for null-terminator
2. Prevents overflow into type field
3. Maintains maximum valid name length (RT_NAME_MAX-1 + '\0')

Regular macro definitions according to [1].
Note: for variadic macros such as MSH_CMD_EXPORT, we can
not use normal @param command, otherwise doxygen will
report "@param is not found in the argument list of ...".
So I just write the parameters by manual.
