2016-11-02	Wait for WIP to clear before returning from erase operations too.	Rob Austein
	Wrong-block-type race condition errors went away after adding the WIP check after flash write operations, then came back once (isolated incident) while running a series of tests which had written enough flash blocks that ks_flash may have finally had to erase something rather than just zeroing. Code inspection confirmed that the erase code was not waiting for WIP to clear before exiting. Difficult to prove that this was the cause of an unreproducible failure, but seems like a likely candidate given previous behavior and change should be harmless, so adding it. Timeout for this flag check is 2000 ms, which is what other erase-related WIP flag checks were already using.
2016-11-01	Tweak CLI keystore commands for latest libhal RPC keystore API.	Rob Austein
	Using {-1} as a client handle in the CLI is a kludge, but the new stricter libhal keystore code really wants us to be consistent about this, so as long as any part of the CLI is using client {-1}, it all needs to do so. This still isn't really right, the CLI probably needs a different set of access rules than those which apply to the RPC calls, but I'm deferring that until we know what the "final" (for this branch) version of the RPC API looks like, and have done whatever refactoring might be required in the libhal keystore drivers.
2016-11-01	Don't return from flash write calls until WIP flag clears.	Rob Austein
	Absence of this check created a nasty race condition in sw/libhal/ks_flash.c, which didn't show up until we had test code which attempted to delete a long series of keys in quick succession. I'm not aware of any sane reason why we would ever want to skip this check, so it's unconditional and applies to all of the SPI flash code, not just the keystore flash code.

2016-10-07	strcasecmp() is not a standard function.	Rob Austein

2016-09-27	"keystore erase" now clears entire keystore flash.	Rob Austein
	Now that we're using more than just the first few sectors of the keystore flash, we need a command to clear the whole thing. This is not quite right yet, because it doesn't yet notify libhal's ks_flash driver that the entire content of the flash has been yanked out from under it. In theory, we should be able to erase the entire flash in a single operation using the bulk erase command command (0xC7), but I couldn't get that to do anything (no error reported, no visible effect), so, for now, we erase by sectors.

2016-09-23	Use subsectors instead of sectors in keystore.	Rob Austein

2016-09-20	Still some problem with uart receive under heavy load, so change to a 2-byte ↵	Paul Selkirk
	receive buffer with half-complete callbacks, and raise the dma priority.

2016-09-05	add bit-for-bit testing of FMC address and data bus	Fredrik Thulin

2016-09-02	Whack with club until working with new keystore API.	Rob Austein
	Basic stuff like "keystore show keys", "keystore delete key", and the PIN commands all work with the new keystore code. Some of the management commands are still broken. Some of the old management commands were using libhal-internal APIs for which no real equivalent exists anymore. Some of the old management commands were doing things that, um, never could have worked as written.
2016-09-01	"make clean" needs to use "rm -f" to avoid gratuitous failures.	Rob Austein

2016-08-23	Multi-client testing revealed race conditions in uart receive code	Paul Selkirk
	(dropped characters, improper handoff of message buffers). Fixed by a) changing the uart receiver from interrupt to DMA mode, and b) replacing the dispatch mutex and rpc semaphore with a mail queue (memory pool + message queue).

	as name.
2016-07-09	Clean up the CLI.	Fredrik Thulin
	A lot of the commands were just useful when testing/implementing features for the Alpha. Remove them now that they have been merged to projects/cli-test.
2016-07-09	Integrate test code for MKMIF.	Fredrik Thulin
	There seems to be a timing issue (?) with the MKMIF. If SCLK_DIV is set to a higher value (was: 0x20) then the CLI command "test mkmif" will fail with only occasional success runs. With divisor 0x01, it works most of the time but not allways.
2016-07-09	Merge more code from projects/hsm.	Fredrik Thulin

2016-07-09	Merge branch 'master' of git.cryptech.is.:sw/stm32	Fredrik Thulin

2016-07-08	Add upload from firmware tarball, gussie up command parser, add dire warnings.	Rob Austein
	Command parser now enforces little things like mutually-exclusive required options so we warn users who attempt something silly. Preferred source for uploads is now the firmware tarball installed along with the client software; we still support uploading from an explictly-specified source file, but one must now say "-i file". Updating the bootloader is dangerous, we now say so and also require an additional option before we'll even attempt it. For the record, while testing this I did manage to brick my Alpha and had to use an ST-LINK to recover, exactly as predicted by the new dire warning.
