A boot-time sum does not prove that wake preserves the image or that every initiator obeys the access policy. Record both contracts separately.
What to notice. The cause read comes first; wake preserves SRAM0; both paths hand control to 0x2000_0000.
It resumes the retained SRAM0 image; clearing that memory would destroy the image to resume.
Add all sixteen boot steps with duration and cumulative time. Write a security matrix for each master and destination, then demonstrate any route that remains open. State what a model PASS establishes and what further evidence a closed partition would require.
The sixteen boot steps and their durations in The NanoSoC Boot Flow in Time.
The reset-cause register and the retained SRAM0 image used by the wake path.
The secure column of the address map and the three bus masters (CPU, SBR, DMA stream path).
Deliverable. A boot record of sixteen rows (step, duration, cumulative time) and a security matrix of master by destination region, with the access attribute each master presents.
Pass criterion. The record sums to the documented boot total, the wake path never clears SRAM0, every matrix cell is allowed or refused for a stated reason, and your readiness note says what a model PASS does and does not establish.
The boot record with the sum and the largest single share.
The matrix, with any cell where the outcome depends on software behaviour marked.
What further evidence a closed secure partition would need.
