U-Boot 2013.07 release

Starting today, we’ll begin shipping a version of U-Boot based on main-line 2013.07.

This release is fairly close to main-line U-Boot, but adds support for our Nitrogen6_Lite and other custom boards.

New features include:

• Disables virtual memory before executing go. This is needed for launching Windows Embedded.
• Adds the mtest (memory test) command to our configurations.
• Boot scripts now blank unused frame-buffers 0-3
• Changes CAS latency to address an obscure error during startup of Timesys images when no displays are connected
• Fixes HDMI output through reboot. See this comment for details.

You can grab a binary package that includes support for all of our boards here:

• u-boot-production.tar.gz

If you extract the content to an SD card, you can upgrade like so:

U-Boot > bootfile=u-boot.nitrogen6q ; run upgradeu
