+Description
+===========
+
+The QorIQ® LS1043A processor is NXP's first quad-core, 64-bit Arm®-based
+processor for embedded networking. The LS1023A (two core version) and the
+LS1043A (four core version) deliver greater than 10 Gbps of performance
+in a flexible I/O package supporting fanless designs. This SoC is a
+purpose-built solution for small-form-factor networking and industrial
+applications with BOM optimizations for economic low layer PCB, lower cost
+power supply and single clock design. The new 0.9V versions of the LS1043A
+and LS1023A deliver addition power savings for applications such as Wireless
+LAN and to Power over Ethernet systems.
+
+LS1043ARDB Specification:
+-------------------------
+Memory subsystem:
+	* 2GByte DDR4 SDRAM (32bit bus)
+	* 128 Mbyte NOR flash single-chip memory
+	* 512 Mbyte NAND flash
+	* 16 Mbyte high-speed SPI flash
+	* SD connector to interface with the SD memory card
+
+Ethernet:
+	* XFI 10G port
+	* QSGMII with 4x 1G ports
+	* Two RGMII ports
+
+PCIe:
+	* PCIe2 (Lanes C) to mini-PCIe slot
+	* PCIe3 (Lanes D) to PCIe slot
+
+USB 3.0: two super speed USB 3.0 type A ports
+
+UART: supports two UARTs up to 115200 bps for console
+
+More information are listed in `ls1043`_.

+Boot Sequence
+=============
+
+
+Bootrom --> TF-A BL1 --> TF-A BL2 --> TF-A BL1 --> TF-A BL31
+--> BL32(Tee OS) --> TF-A BL31 --> BL33(u-boot) --> Linux kernel
+
+
+How to build
+============
+
+Build Procedure
+---------------
+
+-  Prepare AARCH64 toolchain.
+
+-  Build u-boot and OPTee firstly, and get binary images: u-boot.bin and tee.bin
+
+-  Build TF-A for Nor boot
+
+   Build bl1:
+
+   .. code:: shell
+
+       CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 bl1
+
+   Build fip:
+
+   .. code:: shell
+
+       CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 fip \
+       BL33=u-boot.bin NEED_BL32=yes BL32=tee.bin SPD=opteed
+
+Deploy TF-A Images
+-----------------
+
+-  Deploy TF-A images on Nor flash Alt Bank.
+
+   .. code:: shell
+
+       => tftp 82000000  bl1.bin
+       => pro off all;era 64100000 +$filesize;cp.b 82000000 64100000 $filesize
+
+       => tftp 82000000  fip.bin
+       => pro off all;era 64120000 +$filesize;cp.b 82000000 64120000 $filesize
+
+   Then change to Alt bank and boot up TF-A:
+
+   .. code:: shell
+
+       => cpld reset altbank
