Asus SRT-AC1900 - How to?

Hi there, (sorry for my bad english)
In supported devices, I found Asus SRT-AC1900 but... how can I install it?
It's a work in progress?

I see no sign of specific support for the SRT-AC1900 in https://git.lede-project.org/?p=source.git&a=search&h=HEAD&st=commit&s=SRT-AC1900 nor in the mailing list.

Maybe listing the SRT-AC1900 as supported is a mistake in the ToH.

Hey man, any progress with the SRT-AC1900 firmware?

Just bought one because it was listed in the LEDE hardware list and has some cool spec's. Can't find the proper firmware files :frowning:
