Does the pcie device show up during boot when
you add and enable the pcie nodes in the dts?
Or is more work required to get at least "lspci" working?

With this addtion, you could just move the ucidef_set_led_wlan entry in front
of engenius,eap1300 device.
Or you could maybe instead place the
linux,default-trigger = "phy0tpt";
property into the DTS (fritzbox-7530:green:wlan's node) to do the same job.

Oh, I think I remember this from the FB4040 as well. It too had 16384 long
caldata. But everything after byte 12064 was just more padding. That why
I cut it down to make sure not to push any garbage into the running firmware,
because from what I remember, the ath10k will take anything from the pre-cal
at face-value.

Oh, so if the urlader1 has the same values as urlader0, you could check the return
status of fritz_cal_extract and if it failed, then follow up with a fallback to read
from the other urlader config area.
something like:
/usr/bin/fritz_cal_extract -i 1 -s 0x3C800 -e 0x208 -l 12064 -o /lib/firmware/$FIRMWARE $(find_mtd_chardev "urlader0") || \

Just a word of warning here. The gpio52 might not be necessary for the
functioning of the attached nand flash. We put this warning in the
MR33's dts:
/*
* There are 18 pins. 15 pins are common between LCD and NAND.
* The QPIC controller arbitrates between LCD and NAND. Of the
* remaining 4, 2 are for NAND and 2 are for LCD exclusively.
*
* The meraki source hints that the bluetooth module claims
* pin 52 as well. But sadly, there's no data whenever this
* is a NAND or LCD exclusive pin or not.

In the future, this will hopefully become a regulator.
But so far there's no support for it upstream. Hence this is fine.

This is strange, is there really a MIBIB partition there? Not that it makes any
difference since we are not going to mess with the bootloaders. But from all the
different Qcom devices I had my hands on, the first partition always contained
the SBL1 (Secondary Bootloader 1). (If it is a copy of the MIBIB, then...
is there another hidden flash chip?! And please give one of the partitions
a (slightly) different name in this case.)

The "qcom,ipq4019"; can be dropped. Upstream dropped them
as well see commit a2501ebfb066 ("ipq40xx: remove qcom,ipq4019 on all devices")

I remember seeing a fritz_tffs_nand_read utility:
https://lists.openwrt.org/pipermail/openwrt-devel/2018-March/011501.html
maybe it could be of use?
