I'm trying to enable pcie support on a sabresd board running the dora 3.10.17 beta bsp.  I enabled PCI support and the freescale i.MX6 PCIe controller, but did not enable EP or RC support.  When the system boots I see this:


i2c i2c-0: IMX I2C adapter registered

i2c i2c-1: IMX I2C adapter registered

i2c i2c-2: IMX I2C adapter registered

pps_core: LinuxPPS API ver. 1 registered

pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo Giometti <>

PTP clock support registered

MIPI CSI2 driver module loaded

Switching to clocksource mxc_timer1

This worked under the 3.10.9 alpha bsp, not sure what I'm missing on the beta.
