[sw/rom] Enable sec_mmio in keymgr driver This commit enables sec_mmio functionality in the keymgr driver. The following values are now tracked by sec_mmio: * KEYMGR_WORKING_STATE_REG_OFFSET * KEYMGR_RESEED_INTERVAL_SHADOWED_REG_OFFSET * KEYMGR_SEALING_SW_BINDING_0_REG_OFFSET[0:7] * KEYMGR_ATTEST_SW_BINDING_0_REG_OFFSET[0:7] * KEYMGR_SW_BINDING_REGWEN_REG_OFFSET * KEYMGR_MAX_CREATOR_KEY_VER_REGWEN_REG_OFFSET * KEYMGR_MAX_CREATOR_KEY_VER_SHADOWED_REG_OFFSET * KEYMGR_MAX_OWNER_INT_KEY_VER_REGWEN_REG_OFFSET * KEYMGR_MAX_OWNER_INT_KEY_VER_SHADOWED_REG_OFFSET The max key version register configuration was moved into a separate function to be able to lock down the creator versus owner intermediate key intermediate values. The keymgr functional test was updated to enable sec_mmio expectation checks during the simulated boot sequence. Signed-off-by: Miguel Osorio <miguelosorio@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.
