+U-Boot for the Boundary Devices Nitrogen6X and
+Freescale i.MX6q SabreLite boards
+
+This file contains information for the port of
+U-Boot to the Boundary Devices Nitrogen6X and
+Freescale i.MX6q SabreLite boards.
+
+1. Boot source, boot from SPI NOR
+---------------------------------
+The configuration in this directory supports both the
+Nitrogen6X and Freescale SabreLite board, but in a
+different fashion from Freescale's implementation in
+board/freescale/mx6qsabrelite.
+
+In particular, this image supports booting from SPI NOR
+and saving the environment to SPI NOR.
+
+It does not support 'boot from SD' at offset 0x400
+except through the 'bmode' command.
+ http://lists.denx.de/pipermail/u-boot/2012-August/131151.html
+
+2. Boots using 6q_bootscript on SATA or SD card
+-----------------------------------------------
+The default bootcmd for these boards is configured
+to look for and source a boot script named '6q_bootscript'
+in the root of the first partition of the following
+devices:
+
+ sata 0
+ mmc 0
+ mmc 1
+
+They're searched in the order listed above, trying both the
+ext2 and fat filesystems.
+
+2. Maintaining the SPI NOR
+--------------------------
+A couple of convenience commands
+
+ clearenv - clear environment to factory default
+ upgradeu - look and source a boot script named
+ '6q_upgrade' to upgrade the U-Boot version
+ in SPI NOR. The search is the same as for
+ 6q_bootscript described above.
+
+3. Display support
+------------------
+U-Boot support for the following displays is configured by
+default:
+
+ HDMI - 1024 x 768 for maximum compatibility
+ Hannstar-XGA - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1)
+ wsvga-lvds - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600)
+ wvga-rgb - 800 x 480 RGB (Boundary p/n Nit6X_800x480)
+
+Since the ipuv3_fb display driver currently supports only a single display,
+this code auto-detects panel by probing the HDMI Phy for Hot Plug Detect
+or the I2C touch controller of the LVDS and RGB displays in the priority
+listed above.
+
+Setting 'panel' environment variable to one of the names above will
+override auto-detection and force activation of the specified panel.
+
+4. Building
+------------
+
+To build U-Boot for the Nitrogen6x or SabreLite board:
+
+ make nitrogen6x_config
+ make u-boot.imx
+
+If you place the u-boot.imx into a single-partition SD card
+along with a binary version of the boot script 6q_upgrade.txt,
+you can program it using 'upgradeu':
+
+ U-Boot> run upgradeu
