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

this can do it nicely.

+# Wayland {#sec-wayland}
+
+While X11 (see [](#sec-x11)) is still the primary display technology
+on NixOS, Wayland support is steadily improving. Where X11 separates the
+X Server and the window manager, on Wayland those are combined: a
+Wayland Compositor is like an X11 window manager, but also embeds the
+Wayland \'Server\' functionality. This means it is sufficient to install
+a Wayland Compositor such as sway without separately enabling a Wayland
+server:
+
+```nix
+programs.sway.enable = true;
+```
+
+This installs the sway compositor along with some essential utilities.
+Now you can start sway from the TTY console.
+
+If you are using a wlroots-based compositor, like sway, and want to be
+able to share your screen, you might want to activate this option:
+
+```nix
+xdg.portal.wlr.enable = true;
+```
+
+and configure Pipewire using
+[](#opt-services.pipewire.enable)
+and related options.
