What changed, and why it matters
This commit simply removes an unused compiler flag named USE_SVC_SHUTDOWN from the firmware build script. There is no functional code change, no bug fix, and no security-relevant behavior altered. It is a routine cleanup.
No security action needed. Treat as normal maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff deletes a single line that added ‘USE_SVC_SHUTDOWN’ to CPPDEFINES_MOD in core/SConscript.firmware. No C/C++/Python source files are modified. The flag is described as unused, so this is a no-op build configuration cleanup.
