[tlul/sram] Add error checker in tlul_adapter_sram

Pull-request #279 adressed #236 in the register interface.
This PR is to add error checker in tlul_adapter_sram.

It adds common TL-UL protocol checker in the sram adapter too.
Also this PR slightly revises the adapter module design to increase
readability of the code and to make data path more streamlined.

Previously tlul_adapter_sram forwarded the request to SRAM interface
even wrsp_error error is detected. Now the module drops the request and
handles internally (push to request fifo but req_o not asserted). Then
it keeps the order then send error response.

OpenTitan

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.

Documentation

The project contains comprehensive documentation of all IPs and tools. You can either access it online or build it locally by following the steps below.

  1. Ensure that you have the required Python modules installed (to be executed in the repository root):
$ sudo apt install python3 python3-pip
$ pip3 install --user -r python-requirements.txt
  1. Execute the build script:
$ ./util/build_docs.py --preview

This compiles the documentation into ./opentitan-docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:5500.
