SPM: Makefile: Add targets to build resource description blobs
The targets cactus and ivy now also build the resource description blobs used by Cactus and Ivy. This is done through a new shell script: generate_dtb.sh Example command line to build a package with Cactus and Ivy: CROSS_COMPILE=aarch64-linux-gnu- make PLAT=fvp \ DEBUG=1 LOG_LEVEL=50 TESTS=spm \ tftf cactus ivy trusted_firmware/tools/sptool/sptool \ -o sp_package.bin \ -i cactus.bin:cactus.dtb \ -i ivy.bin:ivy.dtb Also, add a disclaimer to explain that the current implementation of SPM is a prototype that is going to undergo a lot of rework.
