The ASL code for SMB, FPGA, AMBA bus and the devices on the bus. The SMB and FPGA are represented as Module device. The container object that acts as a bus node in a namespace. It may contain child objects that are devices or buses. The module device is declared using the ACPI0004 hardware identifier (HID). The AMBA is represented as a separate device along with UART.
This patch is applied and tested on v8 model along with "Hanjun Guo" - Convert the fixed clock to ACPI and "Brandon Anderson" - ARM AMBA bus connector resource changes. The sample output logs on v8 model as below
