Both OLPC and CE4100 activate CONFIG_OF. OLPC uses PROMTREE while CE uses FLATTREE. Compiling for OLPC only breaks due to missing flat tree functions and variables. Use proper wrappers and provide an empty x86_flattree_get_config() inline so OF=y FLATTREE=n builds and works. [ tglx: Make it work with HPET_TIMER=n and make a function static ] Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
