The series partially:

Tested-by: Stephen Warren <swarren at wwwdotorg.org>

I tested that on both Harmony and Seaboard, this series didn't seem to
impact existing operation (boot to a command-prompt, load files from an
SD card, produce serial output). I didn't actually test LP0.

Note:

Neither board appears to be able to actually boot a kernel any more,
failing with the following error:

=============
Starting kernel ...

Uncompressing Linux... done, booting the kernel.
Warning: Neither atags nor dtb found
=============

However, this problem is present in u-boot-tegra/master before any
changes in this series.

Tom, do you want me to file an internal bug for this?
