From 9bd76b807636599712b4f932da9b57d5d3e8fad4 Mon Sep 17 00:00:00 2001 From: Goldschmidt Simon Date: Tue, 21 Nov 2017 12:29:56 +0000 Subject: spl: make CONFIG_OF_EMBED pass dts through fdtgrep Building spl with CONFIG_OF_EMBED enabled results in an error message on my board: "SPL image too big". This is because the fdtgrep build step is only executed for CONFIG_OF_SEPARATE. Fix this by moving the fdtgrep build step ('cmd_fdtgreo') from scripts/Makefile.spl to dts/Makefile so that the reduced dtb is available for all kinds of spl builds. The resulting variable name for the embedded device tree blob changes, too, which is why common.h and fdtdec.c have tiny changes.
