Connect DVP to Tiny DMA2/request 11, IRQ15 and the camera pad/reset lifecycle.
Harden shared capture CDC, frame statistics, per-row size validation and HAL
cleanup while preserving the Mini DMA3 binding and existing register ABI.
Add deterministic capture/recovery firmware, source-bound evidence tooling,
focused RTL/host tests and compact netlist acceptance. Preserve SAFE24,
128 KiB main SRAM, private Crypto storage and the locked dependencies.
Retained validation: focused RTL, host/policy checks, Mini firmware, and
ICS55/IHP130 RECOVERY, QVGA, synthesis and boot/DVP netlist checks pass.
Full-system VGA remains historical; long full Icarus and broad regressions
remain deferred. Global publication/format gaps and negative observational
STA are retained, not reported as passing qualification.

- Introduced the PPALite extension, approved on 2026-10-05, detailing its features such as camera-inline Y extraction, RGB565 ordering, and fixed pixel/line sampling.
- Updated the tiny-soc-verification and tiny-soc documentation to reflect the new PPALite extension, including its integration with existing DVP and DMA channels.
- Added comprehensive evidence tables for PPALite phases (PPALITE-P0 to P5) outlining required evidence and current statuses.
- Clarified the relationship between PPALite and existing SPI/PIO extensions, emphasizing that earlier results cannot qualify newly added PPALite logic.
- Enhanced the README files in the RTL directory to specify PPALite's role and requirements in the context of Tiny SoC development.
- Clarified integration details for WS2812 and XPI in respective documentation.
- Updated the SOC family positioning to reflect changes in clock/reset configurations and DMA channels.

- Specified the active execution order for R2 and clarified the implications of the new architecture on performance and integration.
- Added details on the Tiny Gen1 target's shared XPI register/LUT/PHY contract and optional NSS1 PSRAM integration.
- Clarified the memory model to include optional initialized XPI NSS1 PSRAM for whole-frame data.
- Updated the edge I/O section to reflect the alternate DVP V2 camera profile and GPIO allocations.
- Revised the shared services and package specifications to align with the latest P10 refreeze.
- Enhanced the README to include P10 documentation refreeze details, emphasizing DVP V2 contract and PSRAM integration.
- Introduced to define formal properties for the DMA design, ensuring correct behavior under various conditions.
- Created as a testbench for the DMA register interface, implementing APB and AXI4 protocols to validate register operations.
- Added to verify synchronization between RTL and SDK register constants, ensuring consistency across implementations.
- Updated test files to change instances of ribp_if to apb4_if in various test cases, ensuring consistency with the new APB4 interface.
- Modified assertions and checks in tests to reflect the new APB4 naming conventions, including changes in expected output and input files.
- Adjusted the test descriptions to accurately represent the APB4 functionality being tested, particularly in timer, UART, and GPIO tests.
- Ensured that all relevant paths and file names in the tests are updated to point to the new APB4 implementations, maintaining the integrity of the test suite.
- Updated RTL paths in various files to remove the 'ribp' prefix, reflecting the new directory structure.
- Modified test descriptions to remove version indicators (e.g., V2, V3) for clarity and consistency.
- Adjusted file references in scripts and tests to align with the new peripheral and multimedia directory structure.
- Added a new test to ensure repository layout invariants, confirming the absence of deprecated paths.
- Renamed parameters and signals for better clarity (e.g., DVP_PAYLOAD_WIDTH to DvpPayloadWidth).
- Updated signal assignments and logic to maintain consistent naming conventions.
- Changed output signal names in DVP_CAMERA and DVP_CORE modules to follow a unified naming scheme.
- Adjusted the configuration and command handling in dvp_reg and dvp_core modules to reflect new naming.
- Enhanced the formal verification module to align with updated signal names.
- Ensured all changes maintain functionality while improving code maintainability.
- Modified dma_core to accommodate a wider data width for FIFO operations.
- Updated filelists to include new DVP source files and formal verification files.
