This patch adds common elements for ck804-based boards.
changes by file: src/northbridge/amd/amdk8/northbridge.c: Add high tables code ala Stefan's code for the i945. src/southbridge/nvidia/ck804/ck804_lpc.c: Enable High Precision Event Timers. Add pm_base for ACPI. src/southbridge/nvidia/ck804/ck804_fadt.c: Since fadt is only dependent on the Southbridge, add it here. src/southbridge/nvidia/ck804/Config.lb: Compile in ck804_fadt.c Signed-off-by: Myles Watson <mylesgw@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3988 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
