2021-09-13Added ice40mkm.o to the main MakefilePavel V. Shatov (Meister)
2021-09-13This adds two routines, ice40mkm_init() and ice40mkm_configure(). The formerPavel V. Shatov (Meister)
should be called once during startup. The latter configures the iCE40 chip with a bitstream stored in the very end of the main FPGA's configuration memory. It should be called after startup and potentially after MKM bitstream is upgraded.
2021-09-13Function to read data from the main FPGA configuration memory.Pavel V. Shatov (Meister)
2021-09-13Initialize I/O pins of SPI3, which is used to configure iCE40-based MKM.Pavel V. Shatov (Meister)
Note, that SPI3 is alternate function 6, unlike SPI1 & SPI2 which are both AF5.

2021-06-28Revert Peter's hardware flow control patch, as it sometimes causesPaul Selkirk
corruption on the sending side of USART2 (user/RPC) under load.
2020-10-15Ubuntu replaced arm-none-eabi-gdb with gdb-multiarch over 2 years ago, butPaul Selkirk
maybe we're running an old version that still has it? Check for both.
2020-10-15OpenOCD versions since at least 0.9.0 (May 2015) actually do need thePaul Selkirk
'exit' command to terminate the script. Hopefully we're all past using Debian Jessie by now?

2020-05-05Add more RPC tasks for better signing performance.Paul Selkirk
2020-04-29The new keywrap core now talks directly to the MKM, so there are some API ↵Paul Selkirk
changes.

2020-03-09Replace the brutally inefficient fp_to_unsigned_bin with one based onPaul Selkirk
fp_read_unsigned_bin. I thought about patching it directly in sw/thirdparty/libtfm, but ultimately decided to keep that pristine (especially since we verify file checksums there).

2018-12-12Changed FMC initialization code to match the new sync FMC arbiter. RemovedPavel V. Shatov (Meister)
unnecessary code (no more double read, yay!)
2018-12-05Tell 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.
2018-12-03Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in.Paul Selkirk
2018-12-02Clean up the profiling code to the point where I stand a chance ofPaul 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.
2018-11-26Add loop unrolling to bring the profilable mem* functions closer toPaul 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.
2018-11-14Increase cli task, and move it to SDRAM, because main RAM is getting full.Paul Selkirk
2018-09-11Cleanup, move 'keywrap core' command to the hsm project, where it will ↵Paul Selkirk
actually be useful for short-term testing.
2018-09-07Tweak for 60MHz FMC clock.Rob Austein
2018-09-05When erasing the whole keystore, optionally preserve the login PINs.Paul Selkirk
2018-09-04Make 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.
