* Marlin Firmware entry-point. Abandon Hope All Ye Who Enter Here.
* Setup before the program loop:
*
* - Call any special pre-init set for the board
* - Put TMC drivers into Low Power Standby mode
* - Init the serial ports (so setup can be debugged)
* - Set up the kill and suicide pins
* - Prepare (disable) board JTAG and Debug ports
* - Init serial for a connected MKS TFT with WiFi
* - Install Marlin custom Exception Handlers, if set.
* - Init Marlin's HAL interfaces (for SPI, i2c, etc.)
* - Init some optional hardware and features:
* • MAX Thermocouple pins
* • Duet Smart Effector

* - Init the Ethernet Port
* - Init Touch Buttons (for emulated DOGLCD)
* - Adjust the (certainly wrong) current position by the home offset
* - Init the Planner::position (steps) based on current (native) position
* - Initialize more managers and peripherals:
* • Temperatures
* • Print Job Timer
* • Endstops and Endstop Interrupts
* • Stepper ISR - Kind of Important!
* • Servos
* • Servo-based Probe
* • Photograph Pin
* • Laser/Spindle tool Power / PWM
* • Coolant Control
* • Bed Probe
* • Stepper Driver Reset: ENABLE
* • Digipot I2C - Stepper driver current control

* • Enhanced tools or extruders:
* • Switching Extruder
* • Switching Nozzle
* • Parking Extruder
* • Magnetic Parking Extruder
* • Switching Toolhead
* • Electromagnetic Switching Toolhead
* • Watchdog Timer - Also Kind of Important!
* • Closed Loop Controller
* - Run Startup Commands, if defined
* - Tell host to close Host Prompts
* - Test Trinamic driver connections
* - Init Prusa MMU2 filament changer
* - Init and test BL24Cxx EEPROM
* - Init Creality DWIN encoder, show faux progress bar
* - Reset Status Message / Show Service Messages
* - Init MAX7219 LED Matrix
* - Init Direct Stepping (Klipper-style motion control)

* The main Marlin program loop

* Note that no G-codes from the queue can be executed during idle()
* but many G-codes can be called directly anytime like macros.
* - Check whether SD card auto-start is needed now.
* - Check whether SD print finishing is needed now.
* - Run one G-code command from the immediate or main command queue
* and open up one space. Commands in the main queue may come from sd
* card, host, or by direct injection. The queue will continue to fill
* as long as idle() or manage_inactivity() are being called.
