And it didn't work. While the pcie enumeration worked fine.
The QCA9887 was no longer attaching. As soon as the driver was
loaded it failed due to:
[ 8.888466] ath10k_pci 0000:01:00.0: enabling device (0140 -> 0142)

But I think we can fix the problem. Because according to the old
qcom-ipq40xx.dtsi I dug up:
<https://github.com/gl-inet/openwrt-imagebuilder-ipq806x/blob/master/build_dir/target-arm_cortex-a7_uClibc-1.0.14_eabi/linux-ipq806x/linux-3.14.77/arch/arm/boot/dts/qcom-ipq40xx.dtsi#L631>
The non-prefetchable memory area window size should be 0x00d00000.
ranges = <0x81000000 0 0x40200000 0x40200000 0 0x00100000>, /*
downstream I/O */
<0x82000000 0 0x40300000 0x40300000 0
0x00d00000>; /* non-prefetchable memory */
(yes, I'll be preparing a patch for linux-msm-arm. Can you please let
me know if does indeed finally let you enumerate the device?)
