[util] Fix extract_sw_logs.py
Fixes #14636.
Fixes issue encountered in #14858.
Rather than being told which ELF sections to parse and generate a database
from, the script now reads ALL valid sections from the ELF and creates a
database of address and string found at that address. This eliminates the
need to pass sections using the `--rodata-sections` arg in the bazel rules.
This takes care of string constants that reside in other sections (for
example, the `chip_info` which resides in its own `.chip_info` section).
The other bug was in the `get_str_at_addr()` method, which returns
a string (or substring) starting at a particular address. This computation
requires the original length of the string to be known. Since the strings
go through sanitization, the orignal length may change, leading to errors
thrown when printing single whitespace characters, such as
`LOG_INFO("\n")`. The change records the original length of the string
along with the string (as a tuple) at each address.

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.
