+U-Boot for the Gateworks Ventana Product Family boards
+
+This file contains information for the port of U-Boot to the Gateworks
+Ventana Product family boards.
+
+1. Boot source, boot from NAND
+------------------------------
+
+The i.MX6 BOOT ROM expects some structures that provide details of NAND layout
+and bad block information (referred to as 'bootstreams') which are replicated
+multiple times in NAND. The number of replications is configurable through
+board strapping options and eFUSE settings.  The Freescale 'kobs-ng'
+application from the Freescale LTIB BSP, which runs under Linux, must be used
+to program the bootstream in order to setup the replicated headers correctly.
+
+The Gateworks Ventana boards with NAND flash have been factory programmed
+such that their eFUSE settings expect 2 copies of the boostream (this is
+specified by providing kobs-ng with the --search_exponent=1 argument). Once in
+Linux with MTD support for the NAND on /dev/mtd0 you can program the boostream
+with:
+
+kobs-ng init -v -x --search_exponent=1 u-boot.imx
+
+The kobs-ng application uses an imximage (u-boot.imx) which contains the
+Image Vector Table (IVT) and Device Configuration Data (DCD) structures that
+the i.MX6 BOOT ROM requires to boot.  The kobs-ng adds the Firmware
+Configuration Block (FCB) and Discovered Bad Block Table (DBBT).
+
+This information is taken from:
+  http://trac.gateworks.com/wiki/ventana/bootloader#NANDFLASH
+
+More details about the i.MX6 BOOT ROM can be found in the IMX6 reference manual.
+
+2. Build
+--------
+
+There are several Gateworks Ventana boards that share a simliar design but
+vary based on CPU, Memory configuration, and subloaded devices.  Although
+the subloaded devices are handled dynamically in the bootloader using
+factory configured EEPROM data to modify the device-tree, the CPU choice
+(IMX6Q vs IMX6DL) and memory configurations are currently compile-time
+options.
+
+The following Gateworks Ventana configurations exist:
+ gwventanaq1gspi: MX6Q,1GB,SPI FLASH
+ gwventanaq     : MX6Q,512MB,NAND FLASH
+ gwventanaq1g   : MX6Q,1GB,NAND FLASH
+ gwventanadl    : MX6DL,512MB,NAND FLASH
+ gwventanadl1g  : MX6DL,1GB,NAND FLASH
+
+To build U-Boot for the MX6Q,1GB,NAND FLASH for example:
+
+ make gwventanaq1g_config
+ make
