From 953b7e629198fe2eb0adf272fb9140f2a4a51826 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sun, 13 Jun 2010 18:28:54 +0200 Subject: Remove AmigaOneG3SE board The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.
