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.).
