The88F6660 is a Marvell Avanta-LP SoC, currently not supported in OpenWrt and kernel mainline. However there is some work in progress with Marvell Avanta SoCs in the Doozan forum, see:
to my understanding , to make linux firmware image you need a toolchain (openwrt or original Marvell GCC) and target.
target is Board: zte-88F6660 wich is part of alp(family:avanta_lp) ;wich include(SOC : 88f6660 ,88f6650 ,88f6610); part of marvell EBU.
target hardware description file is dts witch include dtsi wich is soc hardware description file.
to make it clear :
2 files :dtsi +dts are feed to toolchain result in firmware.
its possible to use those of armada a375 a38x and edit them ??
the nearist source code i can find(detail soc attributs) is in previous link.
but maybe this board is post using device tree(dt) or fdt (flat device tree).
anyway will need creat some patches to add support to this family/soc/board to openwrt.

Thanks @briz and thanks @danitool
I see that all the components involved have to fit together like a puzzle, and I don't have the knowledge to carry it out, as I said before. At this point, I can only help by testing, but someone else has to be the one to compile the test firmwares. It is a pity because the router is very worth it.
I'm 8086k from doozan. As far as I know, ZTE zxhn F660 is using Marvell 88f6560 SoC which is an ARM9 single core CPU. I do some work on the kernel for MI424WR rev i to make it support F660. Now only PCI-E is not working. It seemed like ZTE have done something to the uboot. I have uploaded the project to github.
ZTE ZXHN F680 is not the same as ZTE ZXHN F660, but they are very similar and it could work. The only similar firmware I found was that of the Turris Omnia, so I loaded it into memory and started it, but it didn't work. If you or someone in the forum has the knowledge to compile a firmware for the ZTE ZXHN F680, I will be a beta tester with pleasure.
The work is much more than just compile it. I would like to see the whole bootlog of it. To create a DTS for 88f6660 is a extremely hard challenge. I guess ZTE doesn't provide the GPL code for this device either. But if the stock firmware uses newer kernel versions, this will be possible.
