ee4dc24f RN	157	When trace is enabled this function parses the SRAT table and\r
	158	traces the ACPI table fields.\r
	159	\r
	160	This function parses the following Resource Allocation Structures:\r
	161	- Processor Local APIC/SAPIC Affinity Structure\r
	162	- Memory Affinity Structure\r
	163	- Processor Local x2APIC Affinity Structure\r
	164	- GICC Affinity Structure\r
	165	\r
	166	This function also performs validation of the ACPI table fields.\r
