The aim of this new module is to contain code that's parsing ACPI tables. For now, only parsing of IORT table is implemented (it's ARM specific table). And since we only need to check whether the table contains SMMU record, the code is very simplified. I've followed the specification published here: https://developer.arm.com/documentation/den0049/latest/ Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Andrea Bolognani <abologna@redhat.com>
