From 60d5973c3c1c868f012d0b62faa44b7c28d56d33 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Tue, 14 Feb 2017 13:03:27 +0100 Subject: [PATCH] MIPS: Alchemy: update cpu feature overrides No advanced MIPS features for Alchemy. This patch shaves additional 43kB off the DB1300 kernel (~0.5% size reduction).
