From f90a9d02401eeeec18a122b61ccccb91244f321c Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 18 Oct 2011 02:10:36 +0200 Subject: [PATCH] PPC: Fail configure when libfdt is not available We have several targets in the PPC tree now that basically require libfdt to function properly, namely the pseries and the e500 targets. This dependency will rather increase than decrease in the future, so I want to make sure that people building shiny new 1.0 actually have libfdt installed to get rid of a few ifdefs in the code. Warning: This patch will likely make configure fail for people who don't select their own --target-list, but don't have libfdt development packages installed. However, we really need this new dependency to move on.
