Subject: [PATCH resend 00/13] acpi: arm: Add IORT Support
Date: Tue, 13 Mar 2018 20:50:06 +0530	[thread overview]
Message-ID: <cover.1520834718.git.mjaggi@caviumnetworks.com> (raw)

From: Manish Jaggi <mjaggi@caviumnetworks.com>

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.

Changes since RFC
- Added more documentation
- Moved code to arch/arm/acpi/ folder
- Lot of fixes for review comments

This patch works with [1] but few modifiations were made
(a) path of acpi_iort.h has changed so fixed to asm/acpi/acpi_iort.h
(b) Macro #define alloc_io_pgtable_ops(f, c, o) in Patch 5 of [1] results in
 -ENOMEM and need to be fixed.
