2020-05-27	supervisor: add a new WATCHDOG_RESET safe mode reason	Sean Cross
	This mode will be used if the board is reset due to the watchdog expiring. Signed-off-by: Sean Cross <sean@xobs.io>
2020-01-17	Refine iMX RT memory layout and add three boards	Scott Shawcroft
	Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475.

2019-12-12	Fix flash write error handling; clean up safe mode message printing	Dan Halbert

2019-11-18	Supervisor: move most of systick to the supervisor	Jeff Epler
	This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up
2019-05-09	Rework safe mode so we can trigger on all resets	Scott Shawcroft

2019-05-08	Update `on_next_reset` for new safe mode.	Scott Shawcroft
	Fixes #1831
2019-04-08	Reorganize board busses into shared-bindings and shared-module.	Scott Shawcroft

2019-04-05	Fix crash when getting board.SPI outside the VM	Scott Shawcroft
	If one of the default pins was already in use it would crash. The internal API has been refined to allow us to get the value without causing an init of the singleton. Fixes #1753
2019-03-12	Enter safe mode when an allocation is attempted on an uninitialized heap.	Scott Shawcroft

2018-12-06	Rework safe mode and have heap overwrite trigger it.	Scott Shawcroft
	This creates a common safe mode mechanic that ports can share. As a result, the nRF52 now has safe mode support as well. The common safe mode adds a 700ms delay at startup where a reset during that window will cause a reset into safe mode. This window is designated by a yellow status pixel and flashing the single led three times. A couple NeoPixel fixes are included for the nRF52 as well. Fixes #1034. Fixes #990. Fixes #615.
