* 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.
