This closes an old gap in system integration testing for the very
complex ARM firmware stacks by adding fairly advanced Replay Protected
Memory Block (RPMB) emulation to the eMMC device model. Key programming
and message authentication are working, so is the write counter. Known
users are happy with the result. What is missing, but not only for RPMB-
related registers, is state persistence across QEMU restarts. This is OK
at this stage for most test scenarios, though, and could still be added
later on.
