[U-Boot] [PATCH V4] Ethernut 5 board support

Add support for the Ethernut 5 open hardware design, based on Atmel's AT91SAM9XE512 SoC.
V4 - Fix several coding style issues. - Move machine type to config file. - Remove use of CONFIG_ATMEL_LEGACY.

Add support for the Ethernut 5 open hardware design, based on Atmel's AT91SAM9XE512 SoC.
Any chance to get this patch reviewed before it's becoming outdated again?
The patch looks good, it is checkpatch-clean, applies cleanly on u-boot.git/master and u-boot-arm.git/master and compiles on current top of tree. All review comments for v3 were addressed, so I think it can be queued for upcoming release. I delegated the patch in patchwork to Albert (ARM custodian, on CC).
Albert, could you look at the patch and queue it. Thanks!
Best regards, Anatolij

It might help to put the responsible custodian on Cc:
Also, sticking to the correct patch format (like putting comments not into the commitm essage, but into the comment section, i. e. _below_ the "---" line) increases your chances.

For information, this patch is now in u-boot/master.
