[Xen-devel] [RFC 00/11] acpi: arm: IORT Support for Xen

[manish.jaggi@xxxxxxxxxx]

From: Manish Jaggi <manish.jaggi@xxxxxxxxxx>

This patch aims to add the support of IORT in Xen. Below is the list
of major components which this patchset provides.
a. Add support for parsing the IORT 
b. Provides API to populate/query requesterid - streamID mappings and
   reuqesterid - deviceid mappings
c. The requesterid - deviceid mappings is used to create the IORT for
   hardware domain (which hides smmu nodes from IORT)
d. iort.c fwnode.h fwspec code is imported from linux and modified.
e. Few kernel helper routines are also imported from linux.

This patchset compiles with [1]  [RFC v4 0/8] SMMUv3 driver.
