-gerrit commit 65bc4edb7b1f263e08b8486a168b211496856e53 Author: Martin Roth <[email protected]> Date: Thu Jan 10 16:40:59 2013 -0700 Hudson: Changes to agesa/hudson FADT for ACPI 3.0 Update the southbridge/amd/agesa/hudson FADT generation for ACPI 3.0 compliance similar to what was done for cimx/SB800/fadt.c in commit 9aa4389. commit 9aa43892e6899b719fe7f4754901a0eae379a934 Author: Martin Roth <[email protected]> Date: Fri May 25 12:23:32 2012 -0600 Update SB800 CIMX FADT According to the datasheet, PMA_CNT_BLK is no longer available and PM2_CNT_BLK should not be used. Setup for these has been removed from the table and .h file.
