From 46b949a067e5babcd9a554c84599a277ce13d822 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Mon, 25 Feb 2019 21:12:44 +0100 Subject: [PATCH] ipq40xx: enlarge PCIe BAR size David Bauer reported that the VDSL modem (attached via PCIe) on his AVM Fritz!Box 7530 was complaining about not having enough space in the BAR. A closer inspection of the old qcom-ipq40xx.dtsi pulled from the GL-iNet repository listed: | qcom,pcie@80000 { | compatible = "qcom,msm_pcie"; | reg = <0x80000 0x2000>, | <0x99000 0x800>, | <0x40000000 0xf1d>, | <0x40000f20 0xa8>, | <0x40100000 0x1000>, | <0x40200000 0x100000>, | <0x40300000 0xd00000>; | reg-names = "parf", "phy", "dm_core", "elbi", | "conf", "io", "bars"; Matching the reg-names with the listed reg leads to <0xd00000> as the size for the "bars".
