powerpc/85xx: Add support for Emerson/Artesyn MVME2500.
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 and has been boot tested.
