Subject: [PATCH] post.mk: Create dependency makefile by makefile rule
Date: Fri, 31 Mar 2017 16:49:54 +0200	[thread overview]
Message-ID: <20170331144954.14269-1-nikolaus.schulz@avionic-design.de> (raw)

Creating the emmc image requires creating the bct file and the
bootloader image first.  These dependencies are written to a makefile
snippet that is created by the gen-image-deps.sh script.  But that
script is only invoked when the rule that creates the emmc image is run,
which is too late for creating the dependencies makefile.

Add a rule to post.mk that tells make how to create the dependencies
makefile; with that in place, make automatically makes the dependency
makefile before executing any other rules.
