plat: imx8mp: Add the basic support for i.MX8MP
The i.MX 8MP Media Applications Processor is part of the growing
i.MX8M family targeting the consumer and industrial market. It brings
an effective Machine Learning and AI accelerator that enables a new
class of applications. It is built in 14LPP to achieve both high
performance and low power consumption and relies on a powerful fully
coherent core complex based on a quad core Arm Cortex-A53 cluster and
Cortex-M7 low-power coprocessor, audio digital signal processor, machine
learning and graphics accelerators.
