Although of course patches 2 & 3 depend on patch 1. So, the process
would have to be:

1) Apply patch 1 to USB tree.
2) Send pull request for USB to main U-Boot repo.
3) Pull request actioned.
4) Wait until latest u-boot/master is picked in u-boot/arm and hence
u-boot/tegra.
5) Apply patches 2 & 3 to the Tegra tree.

That's quite a long round-trip. What's the typical delay between (1) and
(2) or (3) and (4)?

In the Linux kernel, this would be handled by putting patch (1) into a
topic branch on its own, which can then be merged into both the USB
branch and immediately into Tegra's branch. Of course, that all relies
on never rebasing during pull requests (otherwise, the branch with patch
1 might end up being applied as two different commits when merging into
u-boot/master); something which apparently isn't acceptable for U-Boot:-(
