From: Manish Jaggi <manish.ja...@linaro.org>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.
A link to the design document or a copy would have been helpful here. Cheers,
