For the following code, we need to check 'type_attr.form'.
type_attr = DIE.attributes["DW_AT_type"]
base_type_die = dwarfinfo.get_DIE_from_refaddr(xxx)
When type_attr.form==DW_FORM_ref_addr, 'type_attr.value' means
global reference (across compilation units).
When type_attr.form==DW_FORM_ref4, 'type_attr.value' means
local reference (within the same compilation unit).

Add trace points to record transitions of g_nx_initstate and to mark
board early/late initialization boundaries. Also add trace marks for
RESET and PANIC to improve boot-time diagnostics and failure analysis.
Add OSINIT_RESET to indicate system is in reset process.

Add a concise RPMsg documentation covering:
- Overview of RPMsg framework for AMP systems
- Application scenarios (heterogeneous/homogeneous AMP)
- Layered architecture (Services/Framework/Transport/Physical)
- Message encapsulation process
- Workflow: channel establishment, sending and receiving
- Key design considerations (FIFO order, callback blocking)
- Transport layer comparison
All diagrams use ASCII art for portability.

Add a new license configuration option for components that have
custom permissive licenses which are not covered by the standard
license options (BSD, MIT, GPL, etc.).
This option allows projects to explicitly opt-in to using components
with custom permissive licenses that allow free use, modification,
and distribution but may have specific attribution or notice
requirements.
Also update the License Setup documentation section to include
this new option.

Documentation mentioned xiao-esp32c3 which is incorrect. The actual board name in the codebase is esp32c3-xiao. This commit fixes the board name in the documentation to match the directory structure.
Modify ARM64 architecture configuration to disable fork support in protected
build mode (BUILD_PROTECTED). Update ARCH_HAVE_FORK condition from
"!BUILD_KERNEL" to "!BUILD_KERNEL && !BUILD_PROTECTED", ensuring fork is
only available in flat/monolithic builds, not in protected kernel builds.

Introduce a single configuration option to provide strict transmit
priority ordering based on CAN ID.
The intention is to expose the user-visible behavior (strict TX
priority ordering) rather than the underlying implementation details.
Strict priority ordering is only meaningful when hardware transmit
buffer cancellation is available, so splitting this functionality into
separate configuration options was misleading and could result in
partially effective or incorrect configurations.
