| * 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. | |
