So with this commit, support for the following devices may now be possible:
Of course, the commit is for the Siflower Evaluation Board, and is reference only, so you will not find any downloads available or an imagebuilder.
Just getting my head around adding the SFT1200 as a new device.
Ok, I've got GL-iNet's attention, so I'm going to sit on my hands regarding the SFT1200, as they are going to see if they can get this working with their proprietary overlay stuff.
It seems that the switch driver is missing (for GL-iNet's devices).
Which is weird as GL-iNet are the biggest vendor using this chipset, and have been asking for this commit for years.
GL are awaiting for SiFlower to submit the relevant WiFi driver patches to Openwrt.
Fyi: I've put a few sft1200s aside in storage pending future testing possibilities.
BPI-WiFi5 is now available around $16 from AliExpress.
Ordered the BPI, one of these devices should be able to build with the chipset now being in mainline Openwrt.
64MB RAM isn't great though, considering the 8/64 warning.
Be fine as an access point though 
@hecatae @frollic @Amadeus
I still have access to a bunch of second hand gl-sft1200 devices. (128/128)....
GL's cofounder have advised they are working hard on the new kernel stuff from Siflower, I'm happy to wait for them to release an op24 version of their stock firmware for the sft1200.
BPI-WiFi5 arrived, just hunting down a suitable power supply as it came with US.
SINOVOIP have released sources:
Apparently you need Ubuntu 18.04 to build, anyone got a VM to see if it builds?
uboot builds fine on Debian 11, just trying the SDK
I can attempt a build if needed? The github link you pasted shows their build is for openwrt 18.06, this is ancient and deprecated right? Are you investigating if the build can be done against the latest stable openwrt?
I bought a cheap bpi-wifi5 for access point use, but would like stable openwrt on it. I'm interested in openwrt having official support for bpi-wifi5.
Any way I can assist? I see your first post here says the chipset should be supported already?
Thanks.
Anyone got a GL SF1200 to hand, apparently the EVB board that the Openwrt commit references was used in SF1200.
I installed ubuntu 18.04.6 server and ran the instructions at:
Both uboot and openwrt-18.06 build successfully. They produce files:
uboot_main_sfa28_ac28_fullmask__3cc0edbe4.bin 232KB
openwrt1806_main_a28_bpi_sf19a28_fullmask_rel_v1.0.0.bin 6.3MB
What about
a28_bpi_luci2 and a28_bpi_luci2_neutral ?
a month ago, the source was released, and the latest images are bpi_luci2 and bpi_luci2_neutral so you build those with ./make.sh bpi_luci2 etc.
reason being if you look at Sinovoip's wiki, the images are openwrt1806_main_a28_bpi_luci2 and 6,913kb in size.

Trying to see if I can figure out why.
maybe try with just a single core so you can get a better idea of whats happening.
you can see in the error what is failing ..
Makefile:4210: recipe for target 'all-gcc' failed
maybe try again with the good old fashion
make V=s
this may produce a more useful error log
I tried again after editing make.sh to run make -j1 at the end.
I can't see anything yet, but will keep digging.
Here is the full output at the moment:
