2017-07-31	Adapt uart_rx_thread to the post-thread tasking model, because we're still	Paul Selkirk
	subject to the same forces that made it a good idea in the first place. commit 2b6b9f8 Change RPC UART to have a high-priority thread monitoring a large(ish) DMA buffer, because we've observed out-of-order receives under load.
2017-05-02	Merge branch 'init_cleanup' into no-rtos	Paul Selkirk
	Clean up Makefiles and initialization code.
2017-04-30	Merge branch 'ksng' into no-rtos	Rob Austein
	Required minor manual intervention to resolve merge issues git had no way of understanding: git is clever, but not quite clever enough to understand that a commit in branch had removed the entire RTOS that a commit in the other branch was using. No big deal, just a couple of osDelay() calls needing conversion to HAL_Delay() or task_delay().
2017-04-29	Add minimal mutexes to the minimal tasking system	Paul Selkirk

2017-04-27	Replace the RTOS with a simple cooperative tasker.	Paul Selkirk
	There are no priorities and no preemption, so tasks run in a round-robin fashion, and explicitly yield control.
2017-04-26	Add support for hal_sleep().	Rob Austein

2017-04-17	Add a short delay to osMailAlloc, since we're no longer calling it in an ISR.	Paul Selkirk

2017-04-01	Change RPC UART to have a high-priority thread monitoring a large(ish) DMA	Paul Selkirk
	buffer, because we've observed out-of-order receives under load.
2017-03-02	Try to be a bit more robust in the face of normal errors.	Paul Selkirk
	If hal_rpc_server_dispatch() returns an XDR decode error because the request packet was too short, don't call Error_Handler() and kill the dispatch thread, just drop the request. Add more ibuf_queue entries, but don't panic and kill the dispatch thread if we can't get one, just drop the incoming character (which will lead to an XDR decode error if/when we finally get an ibuf).
2017-02-02	Add locking around keystore operations.	Rob Austein

2016-12-19	Merge branch 'master' into ksng.	Rob Austein
	Drag in UART-related changes from master.
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.
2016-08-23	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).
2016-08-11	Multiple threads and multiple cores, to deal with multiple clients.	Paul Selkirk

2016-07-13	probe_cores() finally does the right thing, so we don't have to call it early.	Paul Selkirk

2016-07-07	Drop bad request packets.	Paul Selkirk
	Also, if the UART receive callback fails to re-enable receive (because dispatch_thread is in the middle of transmitting a response), signal dispatch_thread to re-enable receive after it's done.
2016-07-07	Default to one RPC worker thread.	Paul Selkirk

2016-07-06	Add uart_set_default() to make debugging output easier.	Paul Selkirk

2016-06-30	RPC wire format now includes client handle in all requests, and opcode and	Paul Selkirk
	client handle in all responses.
2016-06-14	Import cli-test into hsm pretty much as-is.	Paul Selkirk

2016-06-13	RSA keygen needs even more stack space than I thought.	Paul Selkirk
	Also, it turns out the linker wants to include initializers for sdram variables in the .elf and .bin files, even though it should handle it like bss. So now we manage sdram directly with a pseudo-malloc.
2016-06-09	Put thread stack buffers in SDRAM, because pkey uses a lot of stack.	Paul Selkirk
	Also rearchitect the way we handle RPC requests - have a bunch of waiting dispatch threads rather than continually creating and deleting threads.
2016-06-09	Rename main.c to hsm.c for consistency and a slightly simpler Makefile.	Paul Selkirk
