i.MX6 PCIe root complex activation

[mariocasto]

Hello to everybody,

I'm trying to use PCIe interface. I've enabled System Type  ---> Freescale MXC Implementations  ---> PCI Express support

but I can't see PCIe probing at starting. I also added some print in "imx_pcie_pltfm_probe" function but no print comes out in the kernel init.

Has anybody already had this problem?

Thank you in advance.

Mario

Are you initializing the PCIE platform device in you board init (imx6q_add_pcie())?

I think in ealier kernel versions the PCI driver has been loaded directly using subsys_initcall. Maybe you have forgotten to update your board init during merging later kernel version.

Thank you, I didn't find in the platform configuration file no init for PCIe as in the other files.

So now I added the configuration.
