Philipp Ebensberger 7e62c9707a mimxrt/sdram: Add SDRAM support. 
Adds support for SDRAM via `SEMC` peripheral. SDRAM support can be
enabled in the mpconfigboard.mk file by setting `MICROPY_HW_SDRAM_AVAIL`
to `1` and poviding the size of the RAM via `MICROPY_HW_FLASH_SIZE`.

When SDRAM support is enabled the whole SDRAM is currently used used
for MicroPython heap.

Port of MicroPython to NXP iMX RT 10xx

Currently supports Teensy 4.0 and the i.MX RT1010 EVK board.

Features:

  • REPL over USB VCP
  • machine.Pin

Known issues:

  • pyboard.py doesn't work with files larger than 64 bytes
  • machine.Pin class currently does not support GPIOMUX option of i.MX RT101x variants

TODO:

  • Enable TCM
  • Peripherals (LED, Timers, etc)
