+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”)
