[Xen-devel] [PATCH v4 02/24] arm/acpi: Add placeholder for efi and acpi load address

[Shannon Zhao <zhaoshenglong@xxxxxxxxxx>]

From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

We will create EFI table, memory description table and some of acpi
tables and we're going to map them to kinfo->gnttab_start of Dom0.
Add placeholder for the starting address for loading in DOM0 and the
size of new added tables. Also add a placeholder to store the new
created tables.
