I use i.MX6DL PCIe module as a RootComplex.
After bringing up the PCIe link connected to an endpoint device,
I want to reset the PCIe core in order to re-bringing up .
I hope to use the "core_rst_n" signal to reset the PCIe core.
It is described in Figure 49-9. I/O Interfaces involved in Initialization (IMX6SDLRM)
What kind of registers do I need to set up in order to assert "core_rst_n" signal ?
