|
|
* 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.
