* Name: imxrt_lowsetup

* Description:
* Called at the very beginning of _start. Performs low level
* initialization including setup of the console UART. This UART done
* early so that the serial console is available for debugging very early
* in the boot sequence.

void imxrt_lowsetup(void);
* Name: imxrt_boardinitialize
*
* Description:
* All i.MXRT architectures must provide the following entry point. This
* entry point is called early in the initialization -- after clocking and
* memory have been configured but before caches have been enabled and
* before any devices have been initialized.
