From e169e1e1ae1e75c522f932554890fb0f2f3e9999 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 24 May 2013 16:26:54 +0100 Subject: [PATCH] configure: Require libfdt for arm, ppc, microblaze softmmu targets A number of our softmmu targets (PPC, ARM, Microblaze) now more or less require flattened device tree support for various board models to work correctly. Make libfdt mandatory if the target list includes these, rather than building unhelpful half-functional binaries. Signed-off-by: Peter Maydell Reviewed-by: Edgar E.
