From 0fec53a24a5e5f7ba68d891b68f568b6aeafaca6 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 8 Jan 2006 22:37:46 +0000 Subject: [ARM] Remove EPXA10DB machine support EPXA10DB seems to be uncared for: - the "PLD" code has never been merged - no one has reported that this platform has been broken since at least 2.6.10 - interest seems to have dried up around March 2003. Therefore, remove EPXA10DB support.
