From 12c01e4a05c8e4f4e0c4e8b74fac7824efdc8b41 Mon Sep 17 00:00:00 2001 From: Arnout Vandecappelle Date: Sat, 15 Oct 2016 16:50:56 +0200 Subject: [PATCH] configs/freescale_mpc8315erdb: remove U-Boot build Binutils was locked down to 2.24 because U-Boot 2014.01 didn't build with more recent binutils. However, this doesn't work anymore because binutils 2.24 is deprecated. Current U-Boot 2016.09.01 doesn't work out of the box because the u-boot-nand.img support has been removed. Since updating U-Boot is generally not needed anyway, we just remove the U-Boot support.
