From 395e60cdc292dc0183c6867d34b43f14a373df55 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 9 Apr 2014 20:10:43 +0900 Subject: [PATCH] kbuild: fix a bug in regeneration of linker scripts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In some use cases, SPL linker script was not updated even when it should be. For instance, $ make tricoder_config all [ build complete ] ... modify include/configs/tricoder.h $ make spl/u-boot-spl.lds should be updated in this case, but it wasn't. To fix this problem, linker scripts generation should be handled by $(call if_changed_dep,...) rather than by $(call if_changed,...).
