Integrate the SPI-P2 shared-DMA ABI into the Tiny product: SPI0 at 0x1001D000 with IRQ25 and RCU target16, the four frozen Gen1 ALT routes, latched four-bit source qualification through the fabric and APB CDC, GPIO readiness/ownership guard, and the bounded rs_spi_* HAL with the TINY_SPI_P3_ACCEPTANCE ci_smoke image. Tiny DMA enables V2.2 requests 16/17 with exact fixed FIFO MMIO checks; Mini remains default-disabled and unchanged. Review closure: the DMA AXI4 master stages the origin channel with each burst so final and contended SPI alias bursts stay qualified, the RCU spare feedback bit is tied off for four-state simulators, and the clock-switch quiescence now includes the SPI session. Validation: full Pytest 2097 passed, 0 failed, 1 skipped (optional pypdf); both Tiny profiles pass the SPI-P3 Verilator acceptance (SIM_TEST_PASS cycles=1030088); R2-P7 Verilator acceptance, Mini DMA formal prove and cover, Mini/Tiny lint, Tiny Yosys synthesis, netsim-boot and OpenSTA pass; C format/policy/host tests and RTL format/style checks clean. Evidence and remaining obligations are recorded in docs/ip/spi-verification.md. Tiny Icarus behavioral remains blocked by the pre-existing observer/sv2v defect (routed to the R2 DV owners); Mini smoke synthesis host timeout is skipped per maintainer decision. Human phase acceptance and SPI-P4/P5 remain outstanding; phase_accepted stays false.
