[Xen-devel] [PATCH 0/4] ARM: ACPI: ITS: Add ITS Support for ACPI hardware domain

[Manish Jaggi <mjaggi@xxxxxxxxxx>]

This patch series adds the support of ITS for ACPI hardware domain.
It is tested on staging branch with has ITS v12 patchset by Andre.

I have tried to incorporate the review comments on the RFC v1/v2 patch.
The single patch in RFC is now split into 4 patches. 

Patch1: ARM: ITS: Add translation_id to host_its
 Adds translation_id in host_its data structure, which is populated from 
 translation_id read from firmwar MADT. This value is then programmed into
 local MADT created for hardware domain in patch 4.

Patch2: ARM: ITS: ACPI: Introduce gicv3_its_acpi_init
 Introduces function for its_acpi_init, which calls add_to_host_its_list
 which is a common function also called from _dt variant.

Patch3: ARM: ITS: Deny hardware domain access to its
 Extends the gicv3_iomem_deny to include its regions as well

Patch4: ARM: ACPI: Add ITS to hardware domain MADT
 This patch adds ITS information in hardware domain's MADT table. 
 Also this patch interoduces .get_hwdom_madt_size in gic_hw_operations,
 to return the complete size of MADT table for hardware domain.
