+Booting from QSPI
+-------------------
+Booting from QSPI requires two images, RCW and u-boot-dtb.bin.
+The difference between QSPI boot RCW image and NOR boot image is the PBI
+command sequence for setting the boot location pointer. It's should point
+to the address for u-boot in QSPI flash.
+
+RCW image should be written to the beginning of QSPI flash device.
+Example of using u-boot command
+
+=> sf probe 0:0
+SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 32 MiB
+=> sf erase 0 +<size of rcw image>
+SF: 65536 bytes @ 0x0 Erased: OK
+=> sf write <rcw image in memory> 0 <size of rcw image>
+SF: 164 bytes @ 0x0 Written: OK
+
+To get the QSPI image, build u-boot with QSPI config, for example,
+<board_name>_qspi_defconfig. The image needed is u-boot-dtb.bin.
+The u-boot image should be written to 0x10000(but 0x1000 for LS1043A, LS2080A).
+
+=> sf probe 0:0
+SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 32 MiB
+=> sf erase 10000 +<size of u-boot image>
+SF: 589824 bytes @ 0x10000 Erased: OK
+=> sf write <u-boot image in memory> 10000 <size of u-boot image>
+SF: 580966 bytes @ 0x10000 Written: OK
+
+With these two images in QSPI flash device, the board can boot from QSPI.

+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.
