Add support for the Artesyn MVME2500 Single Board Computer.
The MVME2500 is a 6U form factor VME64 computer with:
- A single Freescale QorIQ P2010 CPU
- 1 GB of DDR3 onboard memory
- Three Gigabit Ethernets
- Five 16550 compatible UARTS
- One USB 2.0 port, one SHDC socket and one SATA connector
- One PCI/PCI eXpress Mezzanine Card (PMC/XMC) Slot
- MultiProcessor Interrupt Controller (MPIC)
- A DS1375T Real Time Clock (RTC) and 512 KB of Non-Volatile Memory
- Two 64 KB EEPROMs
- U-Boot in 16 SPI Flash
This patch is based on linux-3.18-rc6 and has been boot tested.
