* Enable dcache for OCRAM where the VM heap lives. * Add CIRCUITPY_SWO_TRACE for pushing program counters out over the SWO pin via the ITM module in the CPU. Exempt some functions from instrumentation to reduce traffic and allow inlining. * Place more functions in ITCM to handle errors using code in RAM-only and speed up CP. * Use SET and CLEAR registers for digitalio. The SDK does read, mask and write. * Switch to 2MiB reserved for CircuitPython code. Up from 1MiB. * Run USB interrupts during flash erase and write. * Allow storage writes from CP if the USB drive is disabled. * Get perf bench tests running on CircuitPython and increase timeouts so it works when instrumentation is active.
