[ottf] enable context switching between tasks
This commits enables FreeRTOS cooperative scheduling by:
1. invoking a context switch upon encountering a machine-mode ecall, and
2. adding several FreeRTOS wrapper functions to the OTTF API that
simplify the FreeRTOS interface by providing functions to:
a. create additional FreeRTOS tasks,
b. delete the currently running task,
c. cooperatively yield control flow between tasks, and
d. get the name of the task that is currently executing.

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.
