Currently sptool generates a single blob containing all the Secure Partitions, with latest SPM implementation, it is desirable to have individual blobs for each Secure Partition. It allows to leverage packaging and parsing of SP on existing FIP framework. It also allows SP packages coming from different sources. This patch modifies sptool so that it takes number of SP payload pairs as input and generates number of SP blobs instead of a single blob. Each SP blob can optionally have its own header containing offsets and sizes of different payloads along with a SP magic number and version. It is also associated in FIP with a UUID, provided by SP owner. Usage example: sptool -i sp1.bin:sp1.dtb -o sp1.pkg -i sp2.bin:sp2.dtb -o sp2.pkg ...
