Hmm, something doesn't look right here.  Cut-n-paste problem?  Did you
run 'make dtbs' against this?  I get address size errors when I do.

At any rate, I've fixed it up (new version, incorporating my fix and
Andrew's requested change, below) and added it to mvebu/dt, and
for-next.

let me know if it's ok with you and I'll push it tomorrow.

thx,

Jason.

    ARM: kirkwood: add support for OpenBlocks A7 platform

    The OpenBlocks A7 board is designed and sold by PlatHome, and based on
    a Kirkwood 6283 Marvell SoC. It is quite similar to the OpenBlocks A6
    already supported in the kernel, with the following main differences:

     - The A6 uses a RTC on I2C, while the A7 uses the internal SoC RTC.

     - The A6 has one Ethernet port, while the A7 has two Ethernet ports

     - The A6 has only one USB port, while the A7 integrates a USB hub,
       which provides two front-side USB port, and an internal USB port as
       well.

     - The A6 has 512 MB of RAM, while the A7 has 1 GB of RAM.

     - Slightly different GPIOs for some functions.
