The series doesn't appear to apply to u-boot-usb/master, nor to u-boot-tegra/master plus those cherry-picks listed above. Perhaps you can rebase on something (although I'm not sure which branch it's meant to go through) so I can apply/test it? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
