hw/fsi: Aspeed APB2OPB & On-chip peripheral bus This is a part of patchset where IBM's Flexible Service Interface is introduced. An APB-to-OPB bridge enabling access to the OPB from the ARM core in the AST2600. Hardware limitations prevent the OPB from being directly mapped into APB, so all accesses are indirect through the bridge. The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in POWER processors. This now makes an appearance in the ASPEED SoC due to tight integration of the FSI master IP with the OPB, mainly the existence of an MMIO-mapping of the CFAM address straight onto a sub-region of the OPB address space.

hw/fsi: Introduce IBM's Local bus This is a part of patchset where IBM's Flexible Service Interface is introduced. The LBUS is modelled to maintain mapped memory for the devices. The memory is mapped after CFAM config, peek table and FSI slave registers.
