From ef04d82ec637edf37df5e0f8d183348d78d358f7 Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Mon, 4 May 2009 19:26:43 +0000 Subject: The rev 4099 broke ECC boards, they need to have tidy the ECC tags. Myles reverted this change. I think we can return the 4099 back under HAVE_ACPI_RESUME define to make everyone happy (and booting ;).
