[PATCH] mvebu: add Linksys WRT1900AC (Mamba) support

[Imre Kaloz]

The Linksys WRT1900AC (Mamba) is a router that has

- 2 mini-PCIe slots with Marvell 88W8864 radios
- 1 USB 3.0 port
- 1 USB 2.0/eSATAp port
- 2 Ethernet interfaces connected to a 88E6172 switch (1x WAN + 4x LAN)
- 128MB NAND flash
- 256MB RAM

We are moving to a dual license GPL/X11:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/380065

Could you consider to use it too?
The file you based on will be converted, all the author of this
file already have given their acked-by.


In meantime, I will review the content of your patch.

Thanks,

Gregory
