Hello Kishon,
Our iMX6 hardware (imx6q-b850v3.dts) is not booting with latest
linux-next and I could bisect until:
commit 442ec4c04d1235f8c664a74004dae54a7a574d18
Author: Kishon Vijay Abraham I <kishon at ti.com>
Date: Wed Feb 15 18:48:14 2017 +0530
PCI: dwc: all: Split struct pcie_port into host-only and core structures
Which seem to be causing our issues. Our device (imx6q-b850v3.dts) boots
fine with 4.10, and also boots if we disable pcie with:
diff --git a/arch/arm/boot/dts/imx6q-b850v3.dts b/arch/arm/boot/dts/imx6q-b850v3.dts
index 2c1e98e..e655fd7 100644
--- a/arch/arm/boot/dts/imx6q-b850v3.dts
+++ b/arch/arm/boot/dts/imx6q-b850v3.dts
@@ -212,3 +212,8 @@
};
};
};
+
+&pcie {
+ status = "disabled";
+};
But otherwise our system freezes while initializing PCI, see dmesg with
some more information. Is this something specific of our system/dt or
can this be a bug that is affecting others as well?
Kind Regards,
Peter
