The series partially: Tested-by: Stephen Warren 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?
