Yin Fengwei 81435f5504 vm reset: refine platform reset ... We did following to do platform reset: 1. Try ACPI reset first if it's available 2. Then try 0xcf9 reset method 3. if 2 fails, try keyboard reset method This introduces some timing concern which needs be handled carefully. We change it by following: assume the platforms which ACRN could be run on must support either ACPI reset or 0xcf9 reset. And simplify platform reset operation a little bit: If ACPI reset register is generated try ACPI reset else try 0xcf9 reset method Tracked-On: #3609 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com>		2019-09-09 09:49:59 +08:00
