Mbigen means message based interrupt generator. It locate in ITS or out side of ITS. In fact, mbigen is a kind of interrupt controller collects the irq form non-PCI devices and generate msi interrupt. Hisilicon designed mbigen to reduce the wired interrupt number connected to GIC. In these patches, the interrupts from non-PCI devices are named as MBI to distiguish between legacy MSI interrupt from PCI devices. As a kind of MSI interrupt controller, the mbigen is used as a child domain of ITS domain just like PCI devices. So,in order to support the mbigen interrupt controller, the its-gic-v3-its.c and other related files are changed. Change in v2 ---Compared to v1, mbigen domain is used as a child domain of ITS accroding to Marc's advice.So, all changed files related with MSI in v1 are removed. Now, only its domain related files are changed to support this new interrupt controller.
