From 81da012eb0fff1bc5f129202d0c12b1d63a7761a Mon Sep 17 00:00:00 2001 From: Andy Green Date: Mon, 2 Mar 2009 18:51:56 +0000 Subject: rename-gta03-dropped-3d7k-new-moniker.patch GTA03 project is dropped, long live Openmoko 3d7k project. This name was literally generated by picking the first character of the next four car license plates to pass by I am told. The should catch all GTA03 instances except the machine name. I registered a new machine name since the 3d7k is different from original GTA03, the machine number is 2120.
