From 27f680adc65ca08bf72ed85d3a48d1ee70f77c7a Mon Sep 17 00:00:00 2001 From: Mike Crowe Date: Mon, 27 Oct 2008 13:52:49 +0100 Subject: [ARM] 5323/1: Remove outdated empeg documentation. The documents aren't particularly useful anyway and the hardware in question has never run anything newer than a v2.2.14 kernel to my knowledge.
