[entropy_src/rtl] Suppress re-assertion of interrupts The entropy_data and observe FIFOs are cleared with the entropy_src is disabled, but any interrupts saying they have data must be cleared by FW. As noted in issue #11951, there is also a delay between when the IP is disabled and the FIFO is cleared. This means that even when FIFO interrupts are cleared after disabling, the interrupt can reassert itself in this brief delay period. This PR therefore suppresses these interrupt events from retriggering when the IP is disabled. Signed-off-by: Martin Lueker-Boden <martin.lueker-boden@wdc.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.
