  It is needed to design Linux driver, specific for Your PCIe device, which

can configure corresponding address space. This address space may be used for

access Your PCIe device.  

General information about PCI may be found under the link below.

IMX6 specifics are described in i.MX6 Linux Reference Manual.

Also, the i.MX6 Platform SDK – as collection of standalone drivers - may be helpful.
