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

this can do it nicely.

+# parsedmarc {#module-services-parsedmarc}
+[parsedmarc](https://domainaware.github.io/parsedmarc/) is a service
+which parses incoming [DMARC](https://dmarc.org/) reports and stores
+or sends them to a downstream service for further analysis. In
+combination with Elasticsearch, Grafana and the included Grafana
+dashboard, it provides a handy overview of DMARC reports over time.
+
+## Basic usage {#module-services-parsedmarc-basic-usage}
+A very minimal setup which reads incoming reports from an external
+email address and saves them to a local Elasticsearch instance looks
+like this:
+
+```nix
+services.parsedmarc = {
+  enable = true;
+  settings.imap = {
+    host = "imap.example.com";
+    user = "alice@example.com";
+    password = "/path/to/imap_password_file";
+    watch = true;
+  };
+  provision.geoIp = false; # Not recommended!
+};
+```
+
+Note that GeoIP provisioning is disabled in the example for
+simplicity, but should be turned on for fully functional reports.
+
+## Local mail
+Instead of watching an external inbox, a local inbox can be
+automatically provisioned. The recipient's name is by default set to
+`dmarc`, but can be configured in
+[services.parsedmarc.provision.localMail.recipientName](options.html#opt-services.parsedmarc.provision.localMail.recipientName). You
+need to add an MX record pointing to the host. More concretely: for
+the example to work, an MX record needs to be set up for
+`monitoring.example.com` and the complete email address that should be
+configured in the domain's dmarc policy is
+`dmarc@monitoring.example.com`.
+
+```nix
+services.parsedmarc = {
+  enable = true;
+  provision = {
+    localMail = {
+      enable = true;
+      hostname = monitoring.example.com;
+    };
+    geoIp = false; # Not recommended!
+  };
+};
+```
+
+## Grafana and GeoIP
+The reports can be visualized and summarized with parsedmarc's
+official Grafana dashboard. For all views to work, and for the data to
+be complete, GeoIP databases are also required. The following example
+shows a basic deployment where the provisioned Elasticsearch instance
+is automatically added as a Grafana datasource, and the dashboard is
+added to Grafana as well.
+
+```nix
+services.parsedmarc = {
+  enable = true;
+  provision = {
+    localMail = {
+      enable = true;
+      hostname = url;
+    };
+    grafana = {
+      datasource = true;
+      dashboard = true;
+    };
+  };
+};
+
+# Not required, but recommended for full functionality
+services.geoipupdate = {
+  settings = {
+    AccountID = 000000;
+    LicenseKey = "/path/to/license_key_file";
+  };
+};
+
+services.grafana = {
+  enable = true;
+  addr = "0.0.0.0";
+  domain = url;
+  rootUrl = "https://" + url;
+  protocol = "socket";
+  security = {
+    adminUser = "admin";
+    adminPasswordFile = "/path/to/admin_password_file";
+    secretKeyFile = "/path/to/secret_key_file";
+  };
+};
+
+services.nginx = {
+  enable = true;
+  recommendedTlsSettings = true;
+  recommendedOptimisation = true;
+  recommendedGzipSettings = true;
+  recommendedProxySettings = true;
+  upstreams.grafana.servers."unix:/${config.services.grafana.socket}" = {};
+  virtualHosts.${url} = {
+    root = config.services.grafana.staticRootPath;
+    enableACME = true;
+    forceSSL = true;
+    locations."/".tryFiles = "$uri @grafana";
+    locations."@grafana".proxyPass = "http://grafana";
+  };
+};
+users.users.nginx.extraGroups = [ "grafana" ];
