2 * Support for 'mpc5200-simple-platform' compatible boards.

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