[ottf,tests] Migrate crt_test to use OTTF ISRs. The crt_test checks the operations in the testing `rom_ext`'s `flash_crt.S`. Because of this, it does not run within the context of the OTTF. However, the `flash_crt.S` does set the `mtvec` pointer, so ISRs must be present in case an unexpected interrupt is fired. As described in #8015, we plan to deprecate the default ISR handlers in `sw/device/lib/handler.<c,h>` favor of the OTTF ISRs so that only on a single set of default testing ISRs must be maintained. Therefore, this commit migrates the crt_test to make use of the OTTF ISRs. Additionally, this commit makes it possible to use the OTTF ISRs without requiring the OTTF be linked into the test image too. Signed-off-by: Timothy Trippel <ttrippel@google.com>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
