+Overview
+--------
+The LS1021A-IOT is a Freescale reference board that hosts
+the LS1021A SoC.
+
+LS1021AIOT board Overview
+-------------------------
+ - DDR Controller
+ - Supports 1GB un-buffered DDR3L SDRAM discrete
+ devices(32-bit bus) with 4 bit ECC
+ - DDR power supplies 1.35V to all devices with
+ automatic tracking of VTT
+ - Soldered DDR chip
+ - Supprot one fixed speed
+ - Ethernet
+ - Two on-board SGMII 10/100/1G ethernet ports
+ - One Gbit Etherent RGMII interface to 4-ports switch
+ with 4x 10/100/1000 RJ145 ports
+ - CPLD
+ - 8-bit registers in CPLD for system configuration
+ - connected to IFC_AD[0:7]
+ - Power Supplies
+ - 12V@5A DC
+ - SDHC
+ - SDHC port connects directly to a full 8-bit SD/MMC slot
+ - Support for SDIO devices
+ - USB
+ - Two on-board USB 3.0
+ - One on-board USB k22
+ - PCIe
+ - Two MiniPCIe Solts
+ - SATA
+ - Support SATA Connector
+ - AUDIO
+ - AUDIO in and out
+ - I/O Expansion
+ - Arduino Shield Connector
+ - Port0 - CAN/GPIO/Flextimer
+ - Port1 - GPIO/CPLD Expansion
+ - Port2 - SPI/I2C/UART
+
+Memory map

+Boot description
+-----------------
+LS1021A-IOT support two ways of boot:
+Qspi boot and SD boot
+The board doesn't support boot from another
+source without changing any switch/jumper.
