[U-Boot] [RFC PATCH 0/5] WIP Add support for i.MXRT family

[Giulio Benetti]

This patchset is a WIP for adding i.MXRT family.
It provides:
- soc family entry
- pinctrl driver
- serial driver tweaking
- partial sdram controller driver
- imxrt1050-evk board partial support

To get it working as at least SPL and Falcon mode it still needs sdram
controller driver to be finished and clock driver to be done.

I would like to receive some comment from you all since this is my first
big contribution(at least for me it is).

Giulio Benetti (5):
  Add support for the NXP IMXRT10xx SoC family
  pinctrl: add i.MXRT driver
  serial_lpuart: add support for i.MXRT
  ram: add SDRAM driver for i.MXRT SoCs
  Add support for the NXP IMXRT1050-EVK board
