2020-02-26	Some timing tests overflow the meagre 16K CLI task stack, so bump it up for ↵	Paul Selkirk
	that case.

2019-04-09	Rebase branch 'js_keywrap' from masterjs_keywrap	Paul Selkirk

2019-04-06	Remove fmc_[read\|write]_32, since we now memcpy in hal_io_[read\|write].	Paul Selkirk

2019-04-03	Merge branch 'fmc_clk_60mhz' to 'master'	Paul Selkirk

2019-03-31	Remove inclusion of now-deleted hashsig.h	Paul Selkirk

2019-02-28	Report SDRAM usage in `task show`	Paul Selkirk

2019-01-31	Updated FMC initialization code to match changes in FMC arbiter.	Pavel V. Shatov (Meister)

2018-12-12	Rebase branch 'fmc_clk' of git.cryptech.is:sw/stm32 from master	Paul Selkirk

2018-12-12	Whack various bits of sw/stm32 test code to compile on fmc_clk branch.	Rob Austein

2018-12-12	Changed FMC initialization code to match the new sync FMC arbiter. Removed	Pavel V. Shatov (Meister)
	unnecessary code (no more double read, yay!)
2018-12-05	Tell libtfm that the ARM is little-endian, so it can optimize ↵	Paul Selkirk
	fp_read_unsigned_bin(). This enables some overflow-detection code, which fixes CT-01-009. It also saves 484us/call, which adds up to 6.3ms/RSA signature.
2018-12-03	Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in.	Paul Selkirk

2018-12-02	Clean up the profiling code to the point where I stand a chance of	Paul Selkirk
	understanding it 6 months from now. While I'm at it, try to make it a little more efficient (because 50-60% of time in a typical profiling run is spent in the function-entry counting), and collapse profil.c into gmon.c.
2018-11-26	Add loop unrolling to bring the profilable mem* functions closer to	Paul Selkirk
	newlib, because memset is called a LOT in the course of RSA signing, and we need to understand how much time we're actually spending there.
2018-11-14	Increase cli task, and move it to SDRAM, because main RAM is getting full.	Paul Selkirk

2018-09-11	Cleanup, move 'keywrap core' command to the hsm project, where it will ↵	Paul Selkirk
	actually be useful for short-term testing.
2018-09-07	Tweak for 60MHz FMC clock.	Rob Austein

2018-09-05	When erasing the whole keystore, optionally preserve the login PINs.	Paul Selkirk

2018-09-04	Make parsing and display of masterkey values consistent with one another,	Paul Selkirk
	so the user might be able to copy and paste a generated key into the CLI for recovery. Display had been a 32-byte hexdump. Parsing (manual re-entry of the KEK) had been 8 32-bit little-endian values. This has been a pain point for literally two years, albeit at a low enough pain level that I've managed to cringe and ignore it.
2018-08-27	Add startup delay to let fmc bus settle	Paul Selkirk

2018-08-17	Add sanity test for arbitrary size keys, to be really sure the keywrap core ↵	Paul Selkirk
	bank-switched memory works.
2018-08-16	Add timing tests for key unwrap.	Paul Selkirk

2018-08-15	Add support for Joachim's keywrap core.	Paul Selkirk

2018-07-25	Merge branch 'hashsig'	Paul Selkirk

2018-07-24	Add dummy hal_free_static_memory to cli-test, to avoid a link error.	Paul Selkirk
	We really ought to rototill cli-test, but not today.
2018-07-16	Whack various bits of sw/stm32 test code to compile on fmc_clk branch.	Rob Austein

2018-07-07	Changed FMC initialization code to match the new sync FMC arbiter. Removed	Pavel V. Shatov (Meister)
	unnecessary code (no more double read, yay!)
2018-05-27	Script to run a test with HSM profiling.	Rob Austein

2018-05-27	FMC cleanup: constification, gratuitous pointer.	Rob Austein

2018-05-27	Convert FMC I/O functions to static inline.	Rob Austein
	fmc_read_32() and fmc_write_32() get called often enough that it's worth eliminating unnecessary function call overhead.
2018-05-23	Simplify FMC I/O code.	Rob Austein
	We're no longer using a preemptive multitasker, and we're on the Alpha, not the old bridge board, so all we really need to do is read or write one word at a time via a pointer then wait for the GPIO idle pin to light. Well, other than needing to read twice because of a known hardware problem with the STM32. So we dont need to fiddle with IRQ, or use the CMSIS SRAM lock, or....
2018-05-20	Mutex for RSA blinding factors cache.	Rob Austein

2018-05-01	Update and expand README	Paul Selkirk

2018-05-01	Fix mbed vpath not to use explicit (and wrong) paths	Paul Selkirk

2018-04-19	Rebase hashsig from master	Paul Selkirk

2018-04-19	Reconstruct the hashsig hash tree(s) on device restart.	Paul Selkirk
	This can take long enough (several minutes for h=10) that we do it in a background task, which is then converted to an RPC dispatch task. Also add a very limited form of free(), to free the topmost allocation in the sdram "heap". I don't want to deal with real heap management, but I do want to be able to recover memory upon deleting a hashsig key, if it's easy to do so.
2018-04-19	Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txt	Paul Selkirk

2018-04-19	Cleanup: warn of signed/unsigned mismatches in libhal.	Paul Selkirk
	This is from October's cleanup binge, but I forgot to commit it at the time.

2017-12-14	Revert a clean up 'fix' which actually broke FPGA upload.	Paul Selkirk

2017-10-17	Overhaul UART API	Paul Selkirk
	MGMT is the default UART, and no one should have to explicitly refer to the UART unless they need USER (hsm.c:hal_serial_send_char). The default UART is now exposed in the header file, so that the default-using functions can be macros, which saves a few bytes in code space, and a few microseconds in function call overhead.
