Subject: powerpc/p3060qds: Add support for P3060QDS board
The P3060QDS is a Freescale reference board that hosts the six-core P3060 SOC.
The P3060 Processor combines six e500mc Power Architecture processor cores with
high-performance datapath acceleration architecture(DPAA), CoreNet fabric
infrastructure, as well as network and peripheral interfaces.
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
Ethernet:
- 4x1G + 4x1G/2.5G Ethernet controllers
- 2xRGMII + 1xMII, three VSC8641 PHYs on board
- 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 up to four UARTs
RapidIO: Supports two serial RapidIO ports
