Merge tag 'at91-3.5-cleanup' of git://github.com/at91linux/linux-at91 into next/cleanup

Nicolas Ferre <nicolas.ferre@atmel.com> writes:
 First batch of AT91 cleanup for 3.5 kernel.
 - The biggest improvement of this series is the ability to compile several
   AT91 SoCs in one kernel image.
   For now on it's limited to the DT-enabled boards but we can compile all
   the core together.
 - The Kconfig series is stacked before other patches as it is simple and
   non-intrusive. Its goal is to remove too restrictive dependencies on
   SoC names. This will allow to add support for newer SoC seamlessly.
 - Some very "cosmetic" Kconfig changes are also added (entry names,
   comments, etc.).
