The NXP i.MXRT1170 Evaluation Kit (EVK) provides a platform for rapid
evaluation of the i.MXRT, which features NXP's implementation of the Arm
Cortex-M7 and Cortex-M4 core.
The EVK provides 64 MB SDRAM, Micro SD card socket,
USB 2.0 OTG.
This patch aims to support the preliminary booting up features
as follows:
GPIO
LPUART
SD/MMC
SDRAM
