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

|
* 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. |
