From ae897022d7bdf1466584f54655efe89e2f67ca82 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Wed, 7 Oct 2020 15:39:40 +0200 Subject: [PATCH] Makefile: Fix u-boot-nodtb.bin target MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change fixes two issues when building u-boot-nodtb.bin target: * Remove intermediate binary u-boot-nodtb.bin from disk when static_rela call (which modifies u-boot-nodtb.bin binary) failed. It is required because previous objcopy call creates binary and static_rela finish it. * Do not call static_rela cmd when u-boot-nodtb.bin binary was not created/updated by previous objcopy call. Second fix would ensure that u-boot-nodtb.bin binary is not updated when all prerequisites were up-to-date. And therefore final binary u-boot.bin is not updated in case all prerequisites were not modified and were up-to-date. Now running 'make SOURCE_DATE_EPOCH=0 u-boot.bin' second time now does not touch u-boot.bin binary in case nothing was modified, so GNU make can correctly detect that everything is up-to-date.
