Hi, I have a question about how to change a PCIe device's memory address on i.MX6.

Now, I have a PCIe EP device connected to i.MX6 Quad (running Linux 3.14.52) and issuing lspci  command shows the following values for the device:

Memory at 01100000 (32-bit, non-prefetchable) [size=1M]
Memory at 01200000 (32-bit, non-prefetchable) [size=1M]



The question is how can I change these values (01100000/01200000)?

Should I modify device tree or Linux kernel's source code?
