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

2016-06-15	Use a 1-byte DMA buffer for management UART receives.	Paul Selkirk
	It sounds silly, but this gives us completion callbacks, so we don't spend out entire time slice polling the receive buffer for new characters (which kills performance for tasks that are doing real work). Besides, libcli wants to process a character at a time, so uart_cli_read just waits on the completion callback.
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.
2016-06-13	Only the HSM project needs the RTOS; most of the test projects can use the ↵	Paul Selkirk
	STM32 HAL code directly.
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

2016-06-09	Put all the keystore commands under 'keystore' instead.	Fredrik Thulin
	Makes more sense to keep them together, at least in the cli-test.
2016-06-09	updated test-code for keystore functionality	Fredrik Thulin

2016-06-08	Include strings.h, for strcasecmp().	Rob Austein

2016-06-08	Test code for ks_flash in corresponding branch of libhal.	Fredrik Thulin

2016-06-08	bootloader doesn't need stm-fmc either	Fredrik Thulin

2016-06-07	Don't reboot when CLI logout is intended.	Paul Selkirk

2016-06-07	Check the HARDWARE_EARLY_DFU_JUMP flag as soon as possible in the boot process.	Paul Selkirk
	This avoids the situation where the bootloader systick happens during firmware initialization, and freaks out. Also build the bootloader with the minimum resources needed (no RTOS, no SPI, no I2C).
2016-06-06	Use refactored slip/serial code.	Paul Selkirk
	Client daemon sends client ID, echo it back in response.
2016-06-06	Remove the 6-second blue blink for alpha board.	Paul Selkirk

2016-06-06	Remove unused hex file.	Paul Selkirk

2016-06-06	Remove unused projects.	Paul Selkirk

2016-06-02	Merge branch 'ft-uart_it'	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.
2016-06-02	Move the rest of the CLI commands out of cli-test.c.	Fredrik Thulin

2016-06-01	Implement circular buffer UART RX using interrupts.	Fredrik Thulin

2016-06-01	Move FPGA related commands to mgmt-fpga.c	Fredrik Thulin

2016-06-01	Wait for FPGA_DONE on startup (available on Alpha board)	Fredrik Thulin

2016-05-31	Update huart names to reflect change in stm-uart.	Fredrik Thulin

2016-05-27	DFU working - but no signature validation for now.	Fredrik Thulin

2016-05-27	cli_command_root_node: bugfix missing command callback	Fredrik Thulin

2016-05-26	Implement a bootloader.	Fredrik Thulin
	This bootloader is now the application at 0x08000000 (FLASH start), which the STM32 will execute upon reset. The other applications are now loaded at 0x08030000 (128 KB into the flash) and will never get started unless the bootloader has been programmed into flash too.
2016-05-25	More DFU code. This might actually work.	Fredrik Thulin
	The applications to be uploaded using 'dfu upload' have to have another FLASH defined in their linker script. Have to recompile some firmware tomorrow and test if this actually works.
2016-05-25	Merge remote-tracking branch 'origin/master' into ft-dfu-code-loading	Fredrik Thulin

2016-05-24	Merge branch 'master' of git.cryptech.is:sw/stm32	Paul Selkirk

2016-05-24	Add test-mkmif	Paul Selkirk

2016-05-24	non-working code to upload an application and jump to it	Fredrik Thulin
	Committing my work in progress in case someone else wants to help.
2016-05-24	make 'test sdram' take number of iterations as argument	Fredrik Thulin

2016-05-23	SDRAM initialization and test code from Pavel.	Fredrik Thulin
	Integrated into the cli-test program as such: cryptech> test sdram Initializing SDRAM Starting SDRAM test (n = 0) Run sequential write-then-read test for the first chip Run random write-then-read test for the first chip Run sequential write-then-read test for the second chip Run random write-then-read test for the second chip Run interleaved write-then-read test for both chips at once SDRAM test (n = 0) completed SDRAM test completed successfully cryptech>
2016-05-21	Add code to test reading, writing and erasing keystore data.	Fredrik Thulin

2016-05-21	Add code to access the keystore memory (SPI flash).	Fredrik Thulin

2016-05-21	Add some exciting defines to define commans in the CLI.	Fredrik Thulin
	Hopefully, having this excitement now makes adding commands a little bit less exciting from here on.
2016-05-20	Add code to reset FPGA using FPGA_PROGRAM_B and FPGA_INIT_B.	Fredrik Thulin
	Also add code to erase FPGA config memory and check status of FPGA_DONE.
2016-05-19	Fix a warning.	Fredrik Thulin

2016-05-19	Refactor FPGA bitstream upload code.	Fredrik Thulin
	Move the N25Q128 code to it's own file in order to be able to reuse it for the keystore memory code.
2016-05-18	Add FPGA bitstream upload command to cli-test.	Fredrik Thulin
	This code needs more error checking etc. but together with the Python script 'filetransfer', a new bitstream may be loaded into the FPGA config memory like this: filetransfer --fpga /path/to/bitstream The bitstream is identified by 'file' e.g. like this: alpha_test_top.bit: Xilinx BIT data - from alpha_test_top.ncd;UserID=0xFFFFFFFF - for 7a200tfbg484 - built 2016/05/12(13:59:24) - data length 0xe0164
