From 5110bd21b8af4199b8332c0ab0b23367556653d3 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Sun, 31 Aug 2008 20:59:37 -0700 Subject: sparc: remove CONFIG_SUN4 While doing some easy cleanups on the sparc code I noticed that the CONFIG_SUN4 code seems to be worse than the rest - there were some "I don't know how it should work, but the current code definitely cannot work." places. And while I have seen people running Linux on machines like a SPARCstation 5 a few years ago I don't recall having seen sun4 machines, even less ones running Linux.
