cbfstool overloads baseaddress to represent multiple things: 1. Address in SPI flash space 2. Address in host space (for x86 platforms) 3. Offset from end of region (accepted as negative number) This was done so that the different functions that use these addresses/offsets don't need to be aware of what the value represents and can use the helper functions convert_to_from* to get the required values. Thus, even if the user provides a negative value to represent offset from end of region, it was stored as an unsigned integer. There are special checks in convert_to_from_top_aligned which guesses if the value provided is really an offset from the end of region and converts it to an offset from start of region. This has worked okay until now for x86 platforms because there is a single fixed decode window mapping the SPI flash to host address space. However, going forward new platforms might need to support more decode windows that are not contiguous in the host space. Thus, it is important to distinguish between offsets from end of region and addresses in host/SPI flash space and treat them separately. As a first step towards supporting this requirement for multiple decode windows on new platforms, this change handles the negative offset provided as input in dispatch_command before the requested cbfs operation is performed. This change adds baseaddress_input, headeroffset_input and cbfsoffset_input to struct param and converts them to offsets from start of region before storing into baseaddress, headeroffset and cbfsoffset if the inputs are negative. In follow up changes, cbfstool will be extended to add support for multiple decode windows.
