All x86 platforms until now have memory mapped up to a maximum of 16MiB of SPI flash just below 4G boundary in host address space. For newer platforms, cbfstool needs to be able to accommodate additional windows in the host address space for mapping SPI flash size greater than 16MiB. This change adds two input parameters to cbfstool ext-win-base and ext-win-size which a platform can use to provide the details of the extended window in host address space. The extended window does not necessarily have to be contiguous with the standard decode window below 4G. But, it is left upto the platform to ensure that the fmap sections are defined such that they do not cross the window boundary. create_mmap_windows() uses the input parameters from the platform for the extended window and the flash size to determine if extended mmap window is used. If the entire window in host address space is not covered by the SPI flash region below the top 16MiB, then mapping is assumed to be done at the top of the extended window in host space.
