Joachim Strömbergson	8731908cb1	Support incremental builds for the bitstream. ... By patching the UDS and UDI into an already built bitstream, it is now not necessary to rebuild the entire build flow when changing the UDS and the UDI. This lowers re-build times significantly.

Joachim Strömbergson	29fd8338a7	Update the bitstream hash ... Signed-off-by: Joachim Strömbergson <joachim@assured.se>	2024-03-20 14:36:56 +01:00
Joachim Strömbergson	8784a24b33	Change cpu_monitor to security_monitor and to also check RAM ... Change name of cpu_monitor to security_monitor and increase its functionality to include RAM access violations. If addresses in RAM but outside of physical RAM is accessed in any way the security_monitor traps the CPU in the same way as it already did for execution violations.	2024-03-20 14:36:55 +01:00
Joachim Strömbergson	3fb6d66cf3	Add set-only register for the force_trap signal to ensure ... that the device must be reset to get out of trap. This change also breaks a critical path. Signed-off-by: Joachim Strömbergson <joachim@assured.se>	2024-03-20 14:36:55 +01:00

Michael Cardell Widerkrantz	0590445f3d	Add testbench targets on top-level ... The testbenches live in their own Makefiles under hw/application_fpga/core/*/toolruns (except picorv32). Let's add a top-level target to build and run them. In order to run core testbenches, use cd hw/application_fpga make tb or if using Podman: cd contrib make run-tb to run the same target in a container.	2024-03-20 13:47:12 +01:00
Joachim Strömbergson	ea9271292c	Add Icarus Verilog compiler, simulator used by testbenches ... Signed-off-by: Joachim Strömbergson <joachim@assured.se>	2024-03-20 13:47:12 +01:00
dehanj	159b5b052b	Updated readme and docs to point at dev.tillitis.se.	2024-03-19 17:06:34 +01:00
Michael Cardell Widerkrantz	4d4db70590	fw: Change ASLR name in MMIO ... Use _RAM_ADDR_RAND instead of _RAM_ASLR since this is not OS-level ASLR we're talking about. It's address randomization as seen from outside of the CPU, not from the process running inside it. Ordinary ASLR is visible from the CPU.	2024-03-19 14:36:31 +01:00
Michael Cardell Widerkrantz	f40987b138	fw: Change license for use with qemu ... This file is also included in at least qemu (GPL-2.0-or-later) besides tillitis-key1 (GPL-2.0-only) and tkey-libs (GPL-2.0-only) so it's licensed as GPL v2 or later even if the rest of the project is -only.	2024-03-19 14:36:31 +01:00
Michael Cardell Widerkrantz	c48724e115	fw: Change memory constants to defines ... Instead of putting memory constant into an enum we use defines. Use the direct memory address instead of ORing constants together to compute the address. An enum in ISO C is a signed int. Some of are memory addresses are to large to fit in a signed int. This is not a problem since we're not using ISO C (-std=gnu99) but it doesn't look very nice if you turn on pedantic warnings. Also, if someone would use another compiler which at least supports the inline assembly we use, but possible not other GNU extensions, things would probably break.	2024-03-19 14:36:20 +01:00
dehanj	1e34ddcfa6	Update linter to Verilog-2005	2024-03-19 10:45:37 +01:00
Michael Cardell Widerkrantz	746d7f0e0d	Use pedantic warnings ... Use pedantic warnings but still allow inline assembly, so turn off language-extension-token warnings.	2024-03-19 09:25:37 +01:00

Michael Cardell Widerkrantz	e2bd38c540	fw: Remove unusued forever_redflash() ... Since we now use assert() and feed the CPU an unimplemented instruction we have no need for this.	2024-03-18 16:19:59 +01:00
