From 11d496d1562084d4cdd5822d5ef8fc8c176233ea Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 14 Jul 2016 15:41:22 +0200 Subject: [PATCH] target.mk: rework arm architecture level detection Use kernel config as input instead of -march CFLAGS. With this change, -march can be dropped and replaced with more specific optimization flags for better code generation.
