How to use U-Boot on NXP i.MXRT1170 EVK

Build U-Boot for i.MXRT1170 EVK:
```
$ make mrproper
$ make imxrt1170-evk_defconfig
$ make
```
This will generate the SPL image called SPL and the u-boot.img.
Flash the SPL image into the micro SD card:
```
$sudo dd if=SPL of=/dev/sdX bs=1k seek=1 conv=notrunc; sync
```
