powerpc/p3060qds: Add board related support for P3060QDS platform
The P3060QDS is a Freescale reference board for the six-core P3060 SOC.
P3060QDS Board Overview:
Memory subsystem:
- 2G Bytes unbuffered DDR3 SDRAM SO-DIMM(64bit bus)
- 128M Bytes NOR flash single-chip memory
- 16M Bytes SPI flash
- 8K Bytes AT24C64 I2C EEPROM for RCW
Ethernet:
- Eight Ethernet controllers (4x1G + 4x1G/2.5G)
- Three VSC8641 PHYs on board (2xRGMII + 1xMII)
- Suport multiple Vitesse VSC8234 SGMII Cards in Slot1/2/3
PCIe: Two PCI Express 2.0 controllers/ports
USB: Two USB2.0, USB1(TYPE-A) and USB2(TYPE-AB) on board
I2C: Four I2C controllers
UART: Supports two dUARTs up to 115200 bps for console
RapidIO: Two RapidIO, sRIO1 and sRIO2
