2016-09-09	Simplify hal_rpc_pkey_find() by removing `type` argument.	Rob Austein
	Now that key names are UUIDs generated by the HSM, there's no real need to specify type key type when looking up a key, and removing the `type` argument allows a few simplifications of both the internal keystore API and of client code calling the public RPC API.
2016-09-08	New keystore index internal API. Compiles, not yet integrated or tested.	Rob Austein

2016-09-01	Move in-memory keystore from client to server. Whack with club until compiles.	Rob Austein
	Fixes for various minor issues found while integrating with sw/stm32. Moving the in-memory keystore (PKCS #11 session objects, etc) from the client library to the HSM was on the near term to-do list in any case, doing it now turned out to be the easiest way to solve one of the build problems.
2016-09-01	Revised keystore API, part one. Not usable yet.	Rob Austein
	Changes to implement a revised keystore API. This code probably won't even compile properly yet, and almost certainly will not run, but most of the expected changes are complete at this point. Main points: * Key names are now UUIDs, and are generated by the HSM, not the client. * Keystore API no longer assumes that key database is resident in memory (original API was written on the assumption that the keystore flash would be mapped into the HSM CPU's address space, but apparently the board and flash drivers don't really support that). A few other changes have probably crept in, but the bulk of this changeset is just following through implications of the above, some of which percolate all the way back to the public RPC API.
2016-07-06	Return an intelligent error from hal_ks_get_kek.	Paul Selkirk

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.
2016-06-09	some cleanup, and fix delete operation	Fredrik Thulin

2016-06-09	Sort out the redeclaration of HAL_OK with Rob's help.	Fredrik Thulin
	Thanks Rob!
2016-06-09	bugfixes and cleanups, seems to sort-of work now	Fredrik Thulin

2016-06-08	Implement flash keystore storage. Most of it is still untested.	Fredrik Thulin

2016-05-15	Tweak keystore API to allow update-in-place, so hal_ks_rename() will work.	Rob Austein

2016-03-03	Initial implementations of ks_get_kek(). Untested, and none of these	Rob Austein
	are secure (the one in ks_flash.c is a stub, and the others are for cases where we have no secure hardware in which to store the KEK). These are primarily for testing, since in the long run the entire software implementation of AES-keywrap will be replaced by Verilog which never lets software see the unwrapped key. Or so says current theory. For the moment, we just need something that will let us test the rest of the RPC and keystore mechanisms.

2015-12-20	RPC server stuff mostly written. Compiles, not yet tested. RPC	Rob Austein
	public key extraction functions on hold pending ASN.1 cleanup.
