From cf2817a84c2e9bea2c5dfc084bce2f2d2563ac43 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 6 Sep 2007 09:46:23 -0600 Subject: Migrate 5xxx boards from CONFIG_OF_FLAT_TREE to CONFIG_OF_LIBFDT Affects boards: icecube (lite5200), jupiter, motionpro, tqm5200 Tested on: lite5200b Note: the fixup functions have not been moved to a common place. This patch is targeted for immediate merging as in solves a build issue, but the final name/location of the fixups is still subject to debate. I propose to merge this now, and move the fixups in the next merge window to be usable by all targets.
