IORT shows representation of IO topology for ARM based systems. It describes how various components are connected together on parent-child basis e.g. PCI RC -> SMMU -> ITS. Initial support allows to: - register ITS MSI chip along with ITS translation ID and domain token - find registered domain token based on ITS translation ID - find registered domain token corresponding to given PCI device - find PCI device DeviceID based on its RequesterID Additional features like: - devices to SMMU binding - finding platform device DeviceID based on its RequesterID will be added in next series.

As per kbuild test report, this has to be: #ifdef CONFIG_IORT_TABLE Will be fixed in the next version. Regards, Tomasz
