134 function that requires configuring the mux is enabled. The MUX option is
136 over dts config. For instance, if ``CONFIG_CAN`` is enabled, MUX A is selected
137 even if ``mux="B";`` is configured in dts, and an warning would be reported in

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