There could be some memory map devices located in a certain chip select region of the i.MX WEIM. The devices could be attached to a simple bus(for example, a AXI bus) whose root node is one child device tree node of the i.MX WEIM device tree node. There should be a bridge(very likely, software transparent) bewteen the i.MX WEIM and the simple bus. This patch makes the i.MX WEIM driver possible to populate devices on a simple bus. In this way, people may try various IPs(in a FPGA, maybe) outside of i.MX chips with the i.MX WEIM embedded.
