From d2366dfe1d1c0b760022a034ced944784156c9d4 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 17 Apr 2017 09:18:00 -0400 Subject: [PATCH] arm: Warn that starting with v2018.01 gcc-6 or later is required There are more and more cases where if we do not use gcc-6.0 or later we run into problems where our binaries are too large for the targets. Given the prevalence of gcc-6.0 or later toolchains at this point in time, we give notice now that starting with v2018.01 we will require gcc-6 (or later) for ARM.
