From 89d4f98ae90d95716009bb89823118a8cfbb94dd Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 18 Jan 2021 14:06:09 +0100 Subject: ARM: remove zte zx platform The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.
