|
|
+ * 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.
