powerpc/t4qds: Add T4QDS board

The T4240QDS is a high-performance computing evaluation, development and
test platform supporting the T4240 QorIQ Power Architecture™ processor.

SERDES Connections
  32 lanes grouped into four 8-lane banks
  Two “front side” banks dedicated to Ethernet
  Two “back side” banks dedicated to other protocols
DDR Controllers
  Three independant 64-bit DDR3 controllers
  Supports rates up to 2133 MHz data-rate
  Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller
QIXIS System Logic FPGA

Each DDR controller has two DIMM slots. The first slot of each controller
has up to 4 chip selects to support single-, dual- and quad-rank DIMMs.
The second slot has only 2 chip selects to support single- and dual-rank
DIMMs. At any given time, up to total 4 chip selects can be used.

Detail information can be found in doc/README.t4qds

+Overview
+--------
+The T4240QDS is a high-performance computing evaluation, development and test
+platform supporting the T4240 QorIQ™ Power Architecture™ processor. T4240QDS is
+optimized to support the high-bandwidth DDR3 memory ports, as well as the
+highly-configurable SerDes ports. The system is lead-free and RoHS-compliant.
+
+Board Features
+  SERDES Connections
+	32 lanes grouped into four 8-lane banks
+	Two “front side” banks dedicated to Ethernet
+		- High-speed crosspoint switch fabric on selected lanes
+		- Two PCI Express slots with side-band connector supporting
+		- SGMII
+		- XAUI
+		- HiGig
+		- I-pass connectors allow board-to-board and loopback support
+	Two “back side” banks dedicated to other protocols
+		- High-speed crosspoint switch fabric on all lanes
+		- Four PCI Express slots with side-band connector supporting
+		- PCI Express 3.0
+		- SATA 2.0
+		- SRIO 2.0
+		- Supports 4X Aurora debug with two connectors
+  DDR Controllers
+	Three independant 64-bit DDR3 controllers
+	Supports rates of 1866 up to 2133 MHz data-rate
+	Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller
+	DDR power supplies 1.5V to all devices with automatic tracking of VTT.
+	Power software-switchable to 1.35V if software detects all DDR3LP devices.
+	MT9JSF25672AZ-2G1KZESZF has been tested at 1333, 1600, 1867, 2000 and
+	2133MT/s speeds. For 1867MT/s and above, read-to-write turnaround time
+	increases by 1 clock.
+
+  IFC/Local Bus
+	NAND flash: 8-bit, async or sync, up to 2GB.
+	NOR: 16-bit, Address/Data Multiplexed (ADM), up to 128 MB
+	NOR: 8-bit or 16-bit, non-multiplexed, up to 512MB
+		- NOR devices support 16 virtual banks
+	GASIC: Minimal target within Qixis FPGA
+	PromJET rapid memory download support
+	Address demultiplexing handled within FPGA.
+		- Flexible demux allows 8 or 16 bit evaluation.
+	IFC Debug/Development card
+		- Support for 32-bit devices
+  Ethernet
+	Support two on-board RGMII 10/100/1G ethernet ports.
+	SGMII and XAUI support via SERDES block (see above).
+	1588 support via Symmetricom board.
+  QIXIS System Logic FPGA
+	Manages system power and reset sequencing
+	Manages DUT, board, clock, etc. configuration for dynamic shmoo
+	Collects V-I-T data in background for code/power profiling.
+	Supports legacy TMT test features (POSt, IRS, SYSCLK-synchronous assertion)
+	General fault monitoring and logging
+	Runs from ATX “hot” power rails allowing operation while system is off.
+  Clocks
+	System and DDR clock (SYSCLK, “DDRCLK”)
