It produces the fastest settings for the given set of external flashes. Flash size is no longer hard coded so switching flashes with similar capabilities but different sizes should *just work*. This PR also places "ITCM" code in RAM to save the XIP cache for code execution. Further optimization is possible. A blink code.py still requires a number of flash fetches every blink.

StateMachines can now: * read and read while writing * transfer in 1, 2 or 4 byte increments * init pins based on expected defaults automatically * be stopped and restarted * rxfifo can be cleared and rxstalls detected (good for tracking when the reading code isn't keeping up) Fixes #4162 More parens 2021-02-23T02:35:09+00:00 Scott Shawcroft scott@tannewt.org 2021-02-23T02:35:09+00:00 urn:sha1:3fdf29e773852367ce433ffc9a3a5bbd7b3f379e Board specific flash sizes for RP2040 2021-02-23T01:19:18+00:00 Scott Shawcroft scott@tannewt.org 2021-02-23T01:19:18+00:00 urn:sha1:0aafeac20915fc2844f009cc210c76a4fec32c55 Stop-gap solution for #4041.
