[U-Boot] [PATCH] ventana: Add Gateworks Ventana family support

Tue Jan 21 19:41:00 CET 2014
Gateworks Ventana is a product family based on the i.MX6. This
patch adds support for all boards in the Ventana family. Where
possible, data from the boards EEPROM is used to determine various
details about the board at runtime.

+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 headers 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
+
+This information is taken from
+
+https://trac.gateworks.com/wiki/ventana%3Abuild_uboot
+
+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 u-boot.imx
