2016-07-05	Attempt to add resource management, for multiple cores of the same type.	Paul Selkirk
	Find a suitable core, and mark it busy. Don't forget to release it as soon as you're done. This has a knock-on effect of un-const'ing core arguments and struct fields in a lot of places, and it moves some core checks around.
2016-06-24	Use hal_error_t as suggested by Rob.	Fredrik Thulin

2016-06-23	Implement master key for wrapping keys in the keystore.	Fredrik Thulin
	The KEK (Key Encryption Key) is first fetched from the FPGA that gets it from the volatile Master Key Memory (that in theory has tamper*kek_len = len protection with wiping), and secondly from flash. The flash option is meant for development/evaluation use using an Alpha board where the Master Key Memory is not battery backed. For any serious use of an Alpha, an option is to enter the master key into the volatile MKM on each power-on as a way to unlock the keystore.
