+Subject: [PATCH] template: Fix alignment
+
+The assembler complains about unaliged data:
+
+ ./template.S: Assembler messages:
+ ./template.S:21: Error: misaligned data
+
+If the included data is not an aligned size, the the symbols following
+will be unaligned.
+
+We lost the alignment directive in commit 5f3deee1289e ("template: new
+libfdt requires 8-byte aligned fdt"), so add it back as it was before
+that commit.
+
+Reported by the buildroot autobuilder.
+
+Signed-off-by: Joel Stanley <joel@jms.id.au>
