Add optional Tiny NSS1 PSRAM initialization, identity and geometry checks, mapped CPU/DMA workload coverage, and retained pin-level device verification. Harden shared XPI byte lanes, burst boundaries, response completion and timeout behavior while preserving NOR/SRAM-only boot and Mini compatibility.\n\nValidation: focused P8/XPI tests, ICS55 and IHP130 Verilator P8 replays, Tiny netlist boot, synthesis and observational STA completed. Full long-running Icarus firmware remains deferred to final Tiny qualification.
