Thank you Alex for bringing this up.
Initial support (interrupt controller, clocksource, read-only flash support) is completed in https://github.com/openwrt/openwrt/pull/17928 and is awaiting review. Regarding the PCI and USB, I think it's realistic to expect them fairly soon, as they seem to be standard devices with just some custom clock and reset rituals to get them working. The elephant in the room is Ethernet, but the work done on the airoha/AN7581 Ethernet has definitely changed it from a dream to a possibility. Regarding XPON, the available GPL source is quite complete so I think it's theoretically possible to port, but I'm not sure if we really care. The telcos are all going to 10G or 40G GPON, and there just aren't that many applications for PON that make sense. For me, what's valuable is being able to turn outdated XPON hardware into working wifi routers, and if somebody comes along and wants to do 1Gb PON networks for something like hotels, they can finance the XPON driver port.

We're on a mission to create a new target for a completely new family of SoCs, namely Econet. This project will finally bring mass-adopted fiber routers to OpenWrt. The core switched hands several times, from Trendchip, to Ralink, bought then by Mediatek to form Econet as a spinoff then renamed Airoha. Several github toolchains and SDKs were floating around but were long deprecated so we are starting with a clean room design. We're starting with EN7526 since is the most widely deployed. The first challenge is to start developing the core platform (clocks, timers, PCI, toolchain...). Second is to crack open the XPON subsystem. Might have to deal with binary blobs and create our own OMCI and MBI implementation. So far me, Caleb James DeLisle c...@cjdns.fr and Daniel Danzberger dan...@dd-wrt.com are the only ones knowledgable enough to tackle the platform but will require more so feel free to reach out. A great deal of research and work was done here: https://forum.openwrt.org/t/openwrt-support-for-zyxel-pmg5617ga-first-gpon-support/144231 Thanks, Alex
