[PATCH 00/28] Early flattened DT init consolidation

[Rob Herring <robherring2-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

This is the first of 2 series to do some consolidation of per
architecture Device Tree code. We now have 12 architectures with DT
support. As new architectures have been added, much of the DT related
code for the early flattened DT scanning has been duplicated. Yet little
of this code is architecture specific. This series has 4 main parts:

- Create a common function to copy built-in dtb's out of init section
- Create a single, common function to scan the FDT
- Removal of early_init_dt_setup_initrd_arch
- Create common functions for machine matching with DT

The entire series is available here:
git://sources.calxeda.com/kernel/linux.git dt-cleanup

Compiled on arm, arm64, microblaze, mips, openrisc, powerpc, sparc,
xtensa.
