uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

this can do it nicely.

+# `cypress-example-kitchensink`
+
+This directory 'packages' [cypress-example-kitchensink](https://github.com/cypress-io/cypress-example-kitchensink),
+which is used in `cypress.passthru.tests`.
+
+The app is not really intended for deployment, so I didn't bother with actual packaging, just testing.
+If your real-world app looks like `cypress-example-kitchensink`, you'll want to use Nix multiple outputs so you don't deploy your test videos along with your app.
+Alternatively, you can set it up so that one derivation builds your server exe and another derivation takes that server exe and runs it with the cypress e2e tests.
+
+## Peculiarities
+
+**cypress and Cypress** are distinct names.
+  - `cypress` is the npm module, containing the executable `cypress`
+  - whereas the executable `Cypress` comes from `pkgs.cypress`, a binary distribution (as of writing) by cypress.io.
+
+**updateScript** is not provided for this example project. This seems preferable,
+  because updates to it aren't particularly valuable and have a significant overhead.
+  The goal is to smoke test `cypress`; not run the latest test suite (which it isn't anyway).
+
+## Updating
+
+ - update the hash in `src.nix`
+ - run `regen-nix`
