Arm reference design platforms such as RD-N2 and RD-N2-Cfg1 have multiple I/O virtualization blocks that allow connecting PCIe root bus or non-PCIe (non-discoverable) devices to the system. Each of the I/O virtualization blocks consists of an Arm SMMUv3 compliant MMU-700 controller to handle address translations and a GIC-700 Interrupt Translation Service (ITS) to support message signaled interrupts (MSIs). Platforms can connect various devices to these I/O virtualization blocks through x4/x8/x16 ports exposed by the system. For example, there are two PL011 UART controllers and two PL330 DMA controllers connected to the non-PCIe IO virtualization block on RD-N2 and RD-N2-Cfg1 platforms.
This patch series adds ACPI table support - SSDT and IORT, for Rd-N2 and Rd-N2-Cfg1 platforms to describe the devices connected devices to the I/O virtualization block. The patches also add suppot for platform DXE driver to initialize the UART controllers connected on Rd-N2 and Rd-N2-Cfg1 platforms.
