Add the basic support for i.MX8ULP. The i.MX 8ULP family of processors features NXP’s advanced implementation of the dual Arm Cortex-A35 cores alongside an Arm Cortex-M33. This combined architecture enables the device to run a rich operating system (such as Linux) on the Cortex-A35 core and an RTOS (such as FreeRTOS) on the Cortex-M33 core. It also includes a Cadence Tensilica Fusion DSP for low-power audio and a HiFi4 DSP for advanced audio and machine learning applications.
