From a8b993eb81c142a439c24b871a2317f765fe5397 Mon Sep 17 00:00:00 2001 From: Jon Loeliger Date: Tue, 15 Apr 2014 16:09:37 -0500 Subject: [PATCH] build: Use filechk rules to create and update u-boot.lds Prior to this patch, the top-level linker script u-boot.lds used a simple $(call if_changed) check when generated. That mechanism misses cases where a possible include file change induces a change in the u-boot.lds too. This patch converts it to a stronger check using ($call filechk) that will also notice differences in file contents and will catch changes due to pre-processing as well.
