From 9fa7bbc126d697f1415adbac72bb7f6d978ff50d Mon Sep 17 00:00:00 2001 From: Sascha Silbe <t-uboot@infra-silbe.de> Date: Sun, 11 Aug 2013 16:40:45 +0200 Subject: [PATCH] openrd: fail build if U-Boot would overlap with environment in flash Set CONFIG_BOARD_SIZE_LIMIT so we'll notice at build time if U-Boot has grown so large that it would overlap with the environment area in flash, rather than bricking the device at run-time on first saveenv.
