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

|
used on some devices to allow the CPU to communicate with its
|
|
peripherals.

This subsystem requires driver model.

|
|
help
|
|
Enable compatibility functions for PCI so that old code can be used
|
|
with CONFIG_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.

help
|
|
Enable PCI memory regions to be of multiple entry. Multiple entry
|

here refers to allow more than one count of address ranges for MEMORY

Say Y if base address of system memory is being used as a virtual address

the virtual memory base address to a physical address when adding the PCI

region of type PCI_REGION_SYS_MEMORY.
