This patch adds DM_PCI support to the MVEBU PCIe driver. This is necessary, since all PCI drivers have to be moved to DM (driver model) until the v2019.07 release. To not break git bisect'ablility, this patch also moves CONFIG_PCI_MVEBU from config headers to the defconfig files.

Enable support for PCI (Peripheral Interconnect Bus), a type of bus

peripherals.

|

Use driver model for PCI. Driver model is the new method for
|
|
orgnising devices in U-Boot. For PCI, driver model keeps track of
|

available PCI devices, allows scanning of PCI buses and provides

device configuration support.

Enable compatibility functions for PCI so that old code can be used
|

with CONFIG_DM_PCI enabled. This should be used as an interim

measure when porting a board to use driver model for PCI. Once the

board is fully supported, this option should be disabled.

Support PCI on sandbox, as an emulated bus. This permits testing of

PCI feature such as bus scanning, device configuration and device
