Several other blocks are needed for the types contained in their packages that are used in KMAC interfaces. Also, fix the ROM image scrambling script import paths for Mocha.O
Integrate KMAC hw block for use with the ROM checker only. No other KMAC interfaces are connected. Modify the SW build system to generate a scrambled boot-ROM image. Attempting to run an un-scrambled image will be blocked by the in-hardware ROM checker. Add minimal HJSON files required for ROM image scrambling script. These use the OT testing secrets for now.
