[Qemu-devel] [PATCH 24/26] hw: acpi: reduced: Add SRAT table

[Samuel Ortiz <sameo@linux.intel.com>]

From: Yang Zhong <yang.zhong@intel.com>

If the platform is a NUMA enabled, we add the SRAT table to the ACPI
build. It is up to the calling platform to define its own SRAT build
method or use the aml-build.c one.
