 This file contains information for the port of U-Boot to the Gateworks
 Ventana Product family boards.
 
-1. Boot source, boot from NAND
+1. Secondary Program Loader (SPL)
+---------------------------------
+
+The i.MX6 has a BOOT ROM PPL (Primary Program Loader) which supports loading
+an executable image from various boot devices.
+
+The Gateworks Ventana board config uses an SPL build configuration. This
+will build the following artifacts from u-boot source:
+ - SPL - Secondary Program Loader that the i.MX6 BOOT ROM (Primary Program
+         Loader) boots.  This detects CPU/DRAM configuration, configures
+         The DRAM controller, loads u-boot.img from the detected boot device,
+         and jumps to it.  As this is booted from the PPL, it has an IVT/DCD
+         table.
+ - u-boot.img - The main u-boot core which is u-boot.bin with a image header.
+
+
+2. Build
+--------
+
+To build U-Boot for the Gateworks Ventana product family:
+
+ make gwventana_config
+ make
+
+
+3. 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.
+multiple times in NAND. The number of replications and their spacing (referred
+to as search stride) is configurable through board strapping options and/or
+eFUSE settings (BOOT_SEARCH_COUNT / Pages in block from BOOT_CFG2). In
+addition, the i.MX6 BOOT ROM Flash Configuration Block (FCB) supports two
+copies of a bootloader in flash in the case that a bad block has corrupted one.
+The Freescale 'kobs-ng' application from the Freescale LTIB BSP, which runs
+under Linux and operates on an MTD partition, must be used to program the
+bootstream in order to setup this flash structure 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
+Linux with MTD support for the NAND on /dev/mtd0 you can program the SPL
 with:
 
-kobs-ng init -v -x --search_exponent=1 u-boot.imx
+kobs-ng init -v -x --search_exponent=1 SPL
 
-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).
+The kobs-ng application uses an imximage which contains the Image Vector Table
+(IVT) and Device Configuration Data (DCD) structures that the i.MX6 BOOT ROM

+Discovered Bad Block Table (DBBT).  The SPL build artifact from u-boot is
+an imximage.
 
-This information is taken from:
-  http://trac.gateworks.com/wiki/ventana/bootloader#NANDFLASH
+The u-boot.img, which is the non SPL u-boot binary appended to a u-boot image
+header must be programmed in the NAND flash boot device at an offset hard
+coded in the SPL. For the Ventana boards, this has been chosen to be 14MB.
+The image can be programmed from either u-boot or Linux:
 
-More details about the i.MX6 BOOT ROM can be found in the IMX6 reference manual.

-2. Build
---------
+u-boot:
+Ventana > setenv mtdparts mtdparts=nand:14m(spl),2m(uboot),1m(env),-(rootfs)
+Ventana > tftp ${loadaddr} u-boot.img && nand erase.part uboot && \
+          nand write ${loadaddr} uboot ${filesize}
 
-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.
+Linux:
+nandwrite /dev/mtd1 u-boot.img
 
-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
+The above assumes the default Ventana partitioning scheme which is configured
+via the mtdparts env var:
+ - spl: 14MB
+ - uboot: 2M
+ - env: 1M
+ - rootfs: the rest

@@ -262,3 +263,28 @@ There are two possibilities when preparing an image writable to NAND flash.
 	   In case the user needs to boot a firmware image bigger than 1Mb, the
 	   user has to adjust the "update_nand_firmware_maxsz" variable for the
 	   update scripts to work properly.
+
+5) Installation of U-Boot into SPI NOR flash on a MX28 based board
+------------------------------------------------------------------
+
+The u-boot.sb file can be directly written to SPI NOR from U-boot prompt.
+
+Load u-boot.sb into RAM, this can be done in several ways and one way is to use
+tftp:
+       => tftp u-boot.sb 0x42000000
+
+Probe the SPI NOR flash:
+       => sf probe
+
+(SPI NOR should be succesfully detected in this step)
+
+Erase the blocks where U-boot binary will be written to:
+       => sf erase 0x0 0x80000
+
+Write u-boot.sb to SPI NOR:
+       => sf write 0x42000000 0 0x80000
+
+Power off the board and set the boot mode DIP switches to boot from the SPI NOR
+according to MX28 manual section 12.2.1 (Table 12-2)
+
+Last step is to power up the board and U-boot should start from SPI NOR.
