[sw/silicon_creator] Extend sec_mmio_ctx_t to accommodate 1000 entries At 1616 bytes (~1.6 kiB), `sec_mmio_ctx_t` can currently hold up to 200 entries and its utilization is at ~75% (see [this doc](https://docs.google.com/document/d/1WcXW0r7ffFPQnN-p0mka5512tzWIXYETkc1m9jXuLRc/edit#heading=h.olu7pjrm8gi)). The size of OpenTitan's main SRAM is 128 kiB. In order to be able accommodate additional `sec_mmio` accesses in ROM_EXT without copying older entries to a new table, this commit increases `kSecMmioRegFileSize` from 200 to 1000, increasing the size of `sec_mmio_ctx_t` to 8016 bytes (~8 kiB). Fixes #6609 Signed-off-by: Alphan Ulusoy <alphan@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.
