The series partially:
Tested-by: Stephen Warren <swarren@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?
