The PR summary is OK, but lacks details on the exact changes made. The impact assessment is incomplete. Here's a breakdown of what needs improvement:

Summary - Needs Improvement

• More Detail: Instead of just saying "Add note support," specify what kind of notes are added, how they are triggered, and what information they provide. For example: "Add systemview notes to track watchdog feeding, timeout events, and configuration changes."
• Code Location: Mention the specific files or modules modified (e.g., "Changes made to the wdog driver and the SystemView integration layer").

Impact - Incomplete

• New Feature: Explicitly state that this adds a new feature (systemview watchdog visualization).
• User Impact: While the core functionality doesn't change, users utilizing SystemView for debugging will now have additional insights into the watchdog. This should be mentioned.
• Build Impact: Does enabling this feature require any specific build options or configurations?
• Documentation: Does the PR include documentation updates to explain the new notes and how to use them effectively?

Testing - Insufficient

• Host Details: Provide the operating system and compiler version used for building.
• Target Specificity: Mention the NuttX configuration used on your stm32f429i-disco (e.g., stm32f429i-disco:nsh).
• Logs Missing: The provided example shows a screenshot, but the actual testing logs (both before and after) are absent. Include relevant log snippets demonstrating the changes in SystemView output.

In summary, the PR needs more detail in the summary and impact sections, along with complete testing information to meet the NuttX requirements.
