commit 8e3cd8cccd75e1093821e68f79a59db5211e9b7b Author: Martin Roth martin@se-eng.com Date: Fri Apr 27 11:48:32 2012 -0600
Update amd/south_station/fadt.c with various fixes
This is a model fadt.c that I would like to use for updating several other AMD platforms with after acceptance.
- Updated to match ACPI 3.0b specification and added comments to reflect that. - Since smi_cmd is 0, remove commands that rely on it: acpi_enable, acpi_disable, & pstate_cnt Add comments to that effect. - Changed preferred_pm_profile to SOHO Server (platform specific) - The southstation platform is legacy free - Updated iapc_boot_arch and flags to reflect that. - Added reset_register flag so that operating systems will actually use the reset_reg. This is important on legacy free systems. - Updated Generic Address Structures to use access_size name in the updated acpi.h. Added access sizes to the structures where reasonable. - Removed 64-bit x_firmware_ctl pointer to facs. This was causing a fwts failure and windows-64 BSOD. - Added bit width for pm2_cnt_blk and modified gpe0_blk bit to match the hardware.
