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
