 * Device tree for the AC5X RD Type 7 Com Express carrier board,
 * This specific board in external mode (see below) only maintains
 * a PCIe link with the COM Express CPU module, which does not
 * require any special DTS definitions.
 *
 * AC5X RD can either work as you would expect, as a complete standalone
 * box using the internal CPU, or you can move the switch on the back of
 * the box to "external" mode, and connect via an external cable a kit
 * which would allow it to use an external CPU COM Express module,
 * mounted on top of an interposer kit.
 *
 * So in this case, once the switch is set to external mode as explained above,
 * the AC5X RD becomes part of the carrier solution.
 * This is a development/reference solution, not a full commercial solution,
 * hence it was designed with the flexibility to be configured in different
 * modes of operation.
 *
 * When the board boots in the external CPU mode, the internal CPU is disabled,
 * and only the switch portion of the SOC acts as a PCIe end-point, Hence there
 * is no need to describe this internal (disabled CPU) in the device tree.
 *
 * There is no CPU booting in this mode on the carrier,
 * only on the COM Express CPU module.
