This option enables 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
