U-Boot "cpu" command is used to load and kick Zephyr to Cortex-A secondary Core, Currently
it is supported in : `Real-Time Edge U-Boot`_ (use the branch "uboot_vxxxx.xx-y.y.y,
xxxx.xx is uboot version and y.y.y is Real-Time Edge Software version, for example
"uboot_v2023.04-2.9.0" branch is U-Boot v2023.04 used in Real-Time Edge Software release
v2.9.0), and pre-build images and user guide can be found at `Real-Time Edge Software`_.
