 * Description:
 * This code implements support for a simple MPC52xx based boards which
 * do not need a custom platform specific setup. Such boards are
 * supported assuming the following:
 *
 * - GPIO pins are configured by the firmware,
 * - CDM configuration (clocking) is setup correctly by firmware,
 * - if the 'fsl,has-wdt' property is present in one of the
 *   gpt nodes, then it is safe to use such gpt to reset the board,
 * - PCI is supported if enabled in the kernel configuration
 *   and if there is a PCI bus node defined in the device tree.
 *
 * Boards that are compatible with this generic platform support
 * are listed in a 'board' table.
