===== Overview =====

Quick run-through of the supporting content and files for a specific board; in this case, the hypothetical ZynqMP-based "Coyote" board from Acme Corp, with emphasis on Kbuild structure and not header files wherever possible.

Based on:

<code>
CONFIG_SYS_ARCH="arm"
CONFIG_SYS_CPU="armv8"
CONFIG_SYS_SOC="zynqmp"
CONFIG_SYS_VENDOR="acme"
CONFIG_SYS_BOARD="zynqmp"
CONFIG_SYS_CONFIG_NAME="xilinx_zynqmp"
</code>

===== Files/directories =====

Some of the following will already exist for generic ZynqMP content; use existing files from some other ZynqMP-based board as the starting point for new Coyote-related content.
