 ### Automated Build and Testing
 
-Chromium's testing infrastructure for ARM/Linux is (to say the least)
-in its infancy. There are currently two builders setup, one on the
-FYI waterfall and one the the trybot waterfall:
-
-*   [Linux ARM Cross-Compile](http://build.chromium.org/p/chromium.fyi/builders/Linux%20ARM%20Cross-Compile)
-*   [linux_arm](http://build.chromium.org/p/tryserver.chromium.linux/builders/linux_arm)

 ### Testing with QEMU
 
 If you don't have a real ARM machine, you can test with QEMU. For instance,
