sw/stm32 - Cryptech HSM on STM-32 ARM processor

Age	Commit message (Collapse)	Author
2017-10-15	Cleanup: All drivers return HAL_StatusTypeDef rather than magic values.	Paul Selkirk
	Note: This affects libhal/ks_token.c, which uses the keystore driver directly.
2017-10-11	Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.	Paul Selkirk

2017-02-22	Refactor flash code.	Paul Selkirk

2016-07-21	Use a fresh port of libcli, which retains more of the original API.	Paul Selkirk

2016-07-08	merge test code from projects/hsm/	Fredrik Thulin

2016-06-02	Use DMA for UART RX instead of interrupts.	Fredrik Thulin
	DMA is more efficient and less prone to miss characters than interrupts. An open question is if circular mode is really the best. If someone copy-pastes more than the RX buffer size of configuration into the CLI, we risk the DMA controller catching up with the reader and overwriting data not yet read. Since we don't have flow control back to the users terminal, we will always fail if too much data is entered before we can process it. The question is if failing to stuff new data at the end of a buffer might be better than data being overwritten - thus messing up the commands in unpredictable ways.
