From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alexey Brodkin Date: Fri, 23 Sep 2016 15:07:53 +0300 Subject: [Buildroot] [PATCH] u-boot: Fix building for ARC700 Message-ID: <1474632473-30670-1-git-send-email-abrodkin@synopsys.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net With newer ARC toolchain obsolete -marcXXX were finally deperecated and so compiler throws errors now about unknown option. Solution is as simple as switching to more generic -mcu-XXX options. Which we do. Unfortunately that change in upstream U-Boot [1] happened right after v2016.09 was released an so we need to have that fix for v2016.07 which is mentioned in axs10x defconfigs and for the latest U-Boot release v2016.09 (which is selected by default if no defconfig is used). Once we deprecate either U-Boot version in U-Boot corresponding patch should be removed essentially.
