mimxrt: Add new, minimal port to NXP i.MX RT series CPUs. This is an extremely minimal port to the NXP i.MX RT, in the style of the SAMD port It's largely based on the TinyUSB mimxrt implementation, using the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over the USB-VCP interface. This commit also adds the NXP SDK submodule (also from TinyUSB) to lib/nxp_driver. Note: if you already have the tinyusb submodule initialized recursively you will need to run the following as the tinyusb sub-submodules have been rearranged (upstream): git submodule deinit lib/tinyusb rm -rf .git/modules/lib/tinyusb git submodule update --init lib/tinyusb

mimxrt: Add initial impl of machine.LED class, and basic pin support. This commit implements an LED class with rudimentary parts of a pin C API to support it. The LED class does not yet support setting an intensity. This LED class is put in the machine module for the time being, until a better place is found. One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.

mimxrt: Implement machine.Pin class. - modified pin type from pin_obj_t to machine_pin_obj_t - created machine_pin.c - implemented basic version of make-pins.py to genertate pins.c/.h files automatically; the only alternate function currently supported is GPIO - added af.csv files for all supported MCUs - replaced pins.c/pins.h files with pin.csv for all boards - implemented on/off/high/low/value/init methods - Implemented IN/OUT/OPEN_DRAIN modes - modified LDFLAGS for DEBUG build to get usefull .elf file for debugging Signed-off-by: Philipp Ebensberger

mimxrt/machine_uart: Add the UART class to the machine module. The implementation uses the LPUARTx devices. Up to 8 UARTs can be used, given that the pins are accessible. E.g. 8 on Teensy 4.1, 5 on MIMXRT1020_EVK. For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N. The MIMXRT10xx-EVK boards have only one UART named, which gets the number 1. All other UART are assigned to different Pins: MIMXRT1010-EVK: D0/D1 UART 1 D6/D7 UART 2 A0/D4 UART 3 MIMXRT1020-EVK: D0/D1 UART 1 D6/D9 UART 2 D10/D12 UART 3 D14/D15 UART 4 A0/A1 UART 5 MIMXRT1050-EVK, MIMXRT1060-EVK, MIMXRT1064-EVK: D0/D1 UART 1 D7/D6 UART 2 D8/D9 UART 3 A1/A0 UART 4

mimxrt/machine_spi: Add the SPI class to the machine module. This class supports SPI bus controller mode, with blocking transfers. SPI device numbers start at 0, to comply with the pinout of the Teensy boards. With the configured clock frequency the fastest baud rate is 33MHz. For messages longer 16 bytes DMA is used. The class uses the existing framework with extmod/machine_spi.c. Extended driver options: - drive=n with n being between 1 and 6 or PIN.POWER_1 to PIN.POWER_6. Since the pins used by the SPI are fixed, no Pin settings can be made. Thus the drive option is added allowing to control ringing and crosstalk on the connection. - gap_ns=nnnnn is the time between sent data items in a frame given in ns. Default is 2 clock cycles.

mimxrt: Rework flash configuration. - Moves definition of BOARD_FLASH_SIZE and other header files related to flash configuration into the Makefile. - Adds board specific clock_config.h. - Adds board.h, pin_mux.h, and peripherals.h as they are required by NXP MCU SDK in order to use our own clock_config.h. - Renames board specific FlexSPI configuration files. - Updates flash frequency of MIMXRT1020_EVK - Creates separated flash_config files for QSPI NOR and QSPI Hyper flash. - Unifies VFS start address to be @ 1M for 1010 and 1020 boards. - Unifies 1050EVK boards - Adds support to both NOR and HyperFlash on boards with both capabilities. - Adds automatic FlexRAM initialization to start-up code based on linker script and NXP HAL. - Applies code formatting to all files in mimxrt port. With this change the flash configuration is restructured and organized. This simplifies the configuration process and provides a better overview of each board's settings. With the integration of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better control of the settings and clock configurations. Furthermore the implementation of an explicit FlexRAM setup improves the system performance and allows for performance tuning. Signed-off-by: Philipp Ebensberger

mimxrt/sdcard: Implement SDCard driver. - Configures `PLL2->PFD0` with **198MHz** as base clock of `USDHCx` peripheral. - Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD` - Adds creation of pin defines for SDCard to make-pins.py - Adds new configuration option for SDCard peripheral pinout to mpconfigport.h - Adds interrupt handling support instead of polling - Adds support for `ADMA2` powered data transfer - Configures SDCard to run in HS (high-speed mode) with **50MHz** only! SDCard support is optional and requires `USDHC` peripheral. Thus this driver is not available on `MIMXRT1010_EVK`. SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1` in mpconfigboard.mk. Signed-off-by: Philipp Ebensberger
