From b8c9c8f0190f4004d3d4364edb2dea5978dfc824 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 7 Mar 2018 21:46:52 +0100 Subject: arch: remove score port The Sunplus S+core architecture was added in 2009 by Chen Liqin, who has been co-maintaining it with Lennox Wu since then, but after they both left the company, nobody else has shown any interest in the port and it has seen almost no activity other than tree-wide changes. The gcc port was removed a few years ago due to the inactivity. While the sunplus website still advertises products with unspecified RISC cores that might be S+core based, it's very clear that the Linux port is completely abandoned at this point. This removes all files related to the architecture.
